Japan's land area is about 370,000 square kilometers, and its natural resources are very scarce, with a population of more than 60 million. Together with Korea and Taiwan Province Province, which were enslaved by Japanese control, the population was less than 654.38 billion. However, Japan's scientific and technological level and production capacity are relatively high, with 1936 producing 3.09 million tons of iron and 6.4 million tons of steel. The level and capacity of arms production are very high, and it can manufacture battleships, aircraft carriers, cruisers, fighters, bombers, carrier-based fighters, large-caliber artillery, tanks and armored combat vehicles. During the period of 1937, the annual output of Japanese aircraft was about 600 and tanks were about 200, which could ensure the continuous supply of arms in combat.
At the beginning of the war, Japan could mobilize about 4.48 million military forces, including about 380,000 standing troops, army 17 divisions, naval vessels10.9 million tons, and more than 2,700 air force and naval aircraft. At that time, the Japanese invaders used more than 22,000 divisions, more than 5,800 horses, about 9,500 rifles, more than 600 light and heavy machine guns, 108 guns and 24 tanks.
Before the Lugouqiao Incident on July 7, the Japanese "North China Guard" was composed of 1 infantry brigade and about 6,000 cavalry, artillery and tank soldiers, and its headquarters was in Tianjin. The main force of the Japanese army is stationed in the mainland, Korea and Northeast China, and it is in a state of war. It can be quickly transported to North China through the Beining Railway controlled by it, and transported to the coastal areas of East China by sea.
China's pre-war population was about 450 million, more than six times that of Japan. But at that time, the annual output of iron was less than 654.38 million tons, and the annual output of steel was less than 1000 tons. At that time, the production capacity of the arms industry was very small, and only a small amount of smaller weapons and equipment such as infantry weapons, small caliber mortars and boats could be produced, which could not meet the demand for weapons and equipment in the war at all. Large weapons and equipment, such as aircraft, artillery, tanks, motor vehicles, ships, etc. , can't manufacture, completely dependent on foreign purchase.
When the "July 7th Incident" broke out, the Kuomintang government controlled the national political power with 19 1 division, 52 brigades, more than 59,000 tons of naval vessels and more than 300 air force planes. The total strength of the Kuomintang government is about 2 million, but there are many internal contradictions. Each division of the government forces has more than 65,438+0,000 people, more than 3,800 mounted and fired guns, more than 300 light and heavy machine guns and 46 guns.

At that time, the 29 th Army and the commander Song were stationed in Hebei and were not the direct line of the Kuomintang Central Army. The 29th Army is the headquarters of Feng Yuxiang. 1930, Feng Yuxiang, Yan Xishan and Chiang Kai-shek fought in the Central Plains. Feng retreated, Zhang Xueliang was incorporated, and the designation was changed to the 29 th Army. After Zhang Xueliang gave 29 army 500,000 yuan, he raised the rest of the salary and weapons himself. 29 army's equipment is mostly long guns and old muskets made in Hanyang, and there are no heavy weapons at all. The Northwest Army is good at martial arts, waving broadswords, playing with spears and tying red tassels. Every soldier is brave when carrying it. 29 army was not fully prepared to fight the Japanese army, nor did it have any clear defense deployment and plan. Influenced by the anti-Japanese enthusiasm of the people in North China, patriotic officers and men are determined to fight against the Japanese army.
On the night of July 7th, 70 years ago, the Japanese troops stationed in Fengtai, Beiping, created the July 7th Incident, which totally occupied China. 29 army fought back and War of Resistance against Japanese Aggression, China, broke out.

After Japanese imperialism invaded the northeast of China, based in the northeast, it attempted to attack the Soviet Union to the north and invade China and other countries and regions in Southeast Asia to the south. During the September 18th Incident, there were more than 20,000 Japanese troops in Northeast China. To 1937, there are 6 divisions, 12 divisions. By August of 194 1, the number of Japanese troops deployed in the northeast reached nearly 850,000. And many different types of battlefield fortifications were built, and all the costs of building these fortifications were borne by the puppet government. From1934-65438+August 0945, the fund reached 450 million yuan. Japanese imperialism has been amassing its military strength and preparing for further aggression against China. The most fundamental purpose of Japan's occupation of northeast China is to plunder all kinds of resources in the northeast, turn the northeast into a military base and material support for Japan, and further occupy the whole of China. So let's start by grasping the lifeline of the economy. Railway is the main artery of economy. Starting from 1906, the Japanese seized several railway lines from Russia and established the "Nanman Railway Joint-stock Company". After the September 18th Incident, they gradually seized the railways jointly operated by the China government and China and foreign countries. From 193 1 year1month 10, the kwantung army confessed to "Manchuria Railway" and entrusted it to operate. The power of the Northeast Railway all fell into the hands of the Japanese. Dalian is a place of import and export of materials in Northeast China, which has been operated by Manchuria Railway. After the establishment of the puppet Manchukuo government, all the power of Haikou transportation and inland river transportation was entrusted to Manchuria Railway. Air transport is monopolized by "Manchuria Air Service Company". After the establishment of the puppet Manchu government, it occupied the post office. 1933, "Manzhouli Telephone Service Branch" opened, monopolizing all communication services. Customs and taxation: The Northeast Customs is managed by the General Administration of Taxation controlled by foreigners in Shanghai as collateral for foreign debts such as boxer indemnity. Japan and the puppet Manchukuo repeatedly negotiated with the Shanghai State Administration of Taxation, but they were all rejected. However, in Dalian Customs, both the Commissioner of Customs and the Director of Taxation are Japanese, and 70-80% of the staff are Japanese. The puppet Manchukuo used these people. First, stop paying customs duties to the State Administration of Taxation, then drive away European and American officials and seal up Dalian Customs. Then they seized the exclusive rights of salt tax and other customs. Banks: There used to be four financial institutions in Northeast China called "four bank numbers" to support Northeast finance: the official bank numbers of the three northeastern provinces and the official bank of the northeast local government, with a capital of 20 million yuan; The border bank established by the warlord forces has a capital of 5.25 million yuan; Jilin Forever Crown Bank, the national treasury of the provincial government, with the capital of100,000 yuan; The official bank capital of Heilongjiang Province is 2 million yuan. The four banks have also set up the "Fourth Joint Issuance Reserve Bank of Liaoning Province" in Shenyang, and branches of China Bank and Bank of Communications in the northeast. From the day after the September 18th Incident, the Kwantung Army sent troops to occupy the bank and looted it. They robbed the three northeastern provinces of 160,000 Jin of official silver, and robbed Zhang Xueliang of seven or eight thousand two hundred private gold and antique calligraphy and painting. Some Japanese invaders confessed that they plundered 65.438+0.4 billion yuan from the "Siku". 1932, 1 In July, the puppet Manchukuo Central Bank officially opened, monopolized currency issuance, centralized credit management, controlled the national economy, and plundered the wealth of China people. After the establishment of the puppet Manchukuo government, the Japanese invaders began to plunder. When they felt that the effect was not as good as expected, on May 1937, the puppet Manchukuo government promulgated the Law on the Control of Important Industries and established the Manchuria Heavy Industry Company, and a larger-scale plunder of economic resources began. After the July 7th Incident, due to the needs of the war of aggression, the puppet Manchukuo greatly improved many important product indexes in the first "five-year industrial plan". For example, the number of steel ingots increased from 6.5438+0.85 million tons to 3.65438+0.6 million tons, and 65.438+0.10.2 million tons were shipped to Japan; Pig iron increased from 2.53 million tons to 4.5 million tons, and 6.5438+0.522 million tons were shipped to Japan; Coal increased from 27 1.6 million tons to 3 1.654.38+0 million tons, and transported 6 million tons to Japan; Liquefied coal increased from 800,000 tons to 6.5438+0.77 million tons; The volatile oil increased from 826,000 tons to 6.5438+0.74 million tons, and 6.5438+0.45 million tons were shipped to Japan. Aluminum increased from 20,000 tons to 30,000 tons, and transported to Japan 1.625 million tons; The number of cars increased from 4,000 to 50,000; The number of aircraft has increased from 340 to 30,000. The revision of the above plan not only greatly increases the economic indicators, but also makes the whole production plan an integral part of Japan's economic plan, which is essentially a military plunder plan. 194 1 In September, the puppet Manchukuo government formally determined the second "five-year industrial plan" to support the war of aggression. In this plan, more emphasis is placed on plundering war resources. Compared with the first plan, the second plan must first ensure "Japan's supply" of materials, especially steel and non-metals. Anshan and Benxi Lake are two strongholds where Japanese imperialism plundered the iron and steel resources in Northeast China, and the plundering of iron and steel resources in these two regions did not begin when Japan implemented their first "five-year industrial plan". 193 1 year, Anshan's pig iron output is more than 276,000 tons, second only to the output of Hachiba Iron Works, the largest steel enterprise in Japan at that time. 1933, Towu Province of Japan allowed Manzhouli Iron and Steel Company to transfer the equipment of Anshan Iron and Steel Company to Showa Steel Works wholly owned by Manzhouli Iron and Steel Company to expand the steelmaking equipment based on three blast furnaces of Anshan Iron and Steel Company. By 1937, the annual production capacity of pig iron will be increased to 700,000 tons; The annual output of steel ingots reaches 580,000 tons. By 1943, the pig iron output reached1300,000 tons; The steel production capacity reached 654.38+330,000 tons. 193 1 year, the pig iron output of Benxi Lake is more than 65,000 tons, and 1944 is 370,000 tons. 1937 After the July 7th Incident, the annual output of pig iron in Japan was 2.56 million tons, and that in Manchukuo was about 700,000 tons, totaling 3.26 million tons. Steel, Japan's output of 6.48 million tons, fake 500,000 tons, a total of 6.98 million tons. Thus, the Japanese plundered a lot of war resources from the northeast of China and expanded their armaments. The vast northeast region is rich in coal resources, covering an area of over 65438+300,000 square kilometers. According to the investigation of the geological survey of Manchuria Railway 1932, it is estimated that the coal buried amount in Northeast China is 4.8 billion tons. In the late period of the Puppet Manchukuo, after investigation, Manchukuo Coal Mine Company estimated that the coal buried in Northeast China exceeded 20 billion tons. For a long time, imperialist aggression forces have invaded and plundered the rich coal resources in northeast China. After the Russo-Japanese War, some coal mines were taken over by the Japanese, the most important of which was Fushun. After the Japanese invaders occupied Fushun by force, they infiltrated into another important coal mine-Fuxin Coal Mine (formerly known as Xinqiu Coal Mine) and stole the mining rights. Before the September 18th Incident, the coal mines of Japanese operators were in a monopoly position, while Fushun coal mine was in an absolute advantage.

According to statistics, before the September 18th Incident, the coal output of Fushun Coal Mine reached 78 million tons, 1.929 was 851.900 tons, accounting for 69% of the total coal output in Northeast China. Such a large output of coal is not sold in the northeast market, but exported and transported to local customs, the most important of which is shipped to Japan. Fushun coal shipped to Japan accounts for 50% of the total output of coal mines and can account for 60-70% of Japan's total coal imports. 1929, the coal shipped to Japan was1880,000 tons. After the September 18th Incident, the coal output increased continuously, reaching 1937 to10.34 million tons. Fushun coal has long been regarded as a special topic by the Japanese navy, and almost all of the largest naval factories in Japan, Wu Factory, use Fushun coal. It is said that the steel used to make cannons and warship decks must be smelted with Fushun coal, and no other coal can. At that time, Japan's Bagong Iron Works had more than 20 gas generators for steelmaking. If Fushun medium lump coal is used, it is enough to start 12, and the gas use standard is stable. Fushun coal is considered as the best industrial coal, and it is called "the standard coal of the East" in Japan. Fushun coal is regarded as the standard to judge the quality of other coals. The lack of oil in Japan's economy has become a major obstacle for Japanese militarism to prepare for and carry out war. Like coal, the plundering of oil resources in Northeast China by the Japanese invaders did not begin in the period of the Puppet Manchukuo, but only intensified in the period of the Puppet Manchukuo. The Japanese invaders plundered the oil resources in Northeast China, including natural oil, shale oil and man-made oil, among which the largest scale effect was the plunder of Fushun shale oil. The shale oil in Fushun coal mine is at the top of the coal seam, with a reserve of 5.5 billion tons, which can produce 300 million tons of crude oil, equivalent to 1/5 of the natural oil reserves in the United States at that time. If you consume 4 million tons of heavy oil every year, you can supply it for 75 years. Therefore, Japan attaches great importance to Fushun shale oil resources. 193 1 produces more than 63,000 tons of crude oil. 1935 The annual output of crude oil reached145,000 tons. 1942 the equipment capacity of Fushun coal mine two systems oil plant is 300,000 tons of crude oil/year. 1944 The actual crude oil output was 204,000 tons. During the Puppet Manchukuo period, there were more than 70,000 hectares of cultivated land160,000 hectares of cultivated land and wasteland160,000 hectares in Northeast China. The population engaged in agricultural production accounts for 80% of the residents, and the main grain output reaches18.7 million tons. This is a world-famous grain-producing area with rich agricultural resources and good natural conditions. However, since the September 18th Incident, the political situation has been turbulent, the situation unstable, natural and man-made disasters, a large number of farmers abandoned agriculture, and cultivated land was abandoned. In order to meet the huge needs of the war, the Japanese invaders constantly increased their plundering of grain in an attempt to turn Northeast China into a "grain depot base in Greater East Asia". Carry out the policy of "delivering grain", implement compulsory purchase and sale of grain, and force farmers to sell grain. They pay a small amount of money to farmers in advance, for example, in 194 1 year, they sign a "delivery" contract with farmers for each 100 kg 1 yuan, stipulating the maximum "delivery" amount. In autumn, regardless of the harvest, farmers are forced to pay in full. Private buying and selling of grain, once detected by the police or spies, will not only be confiscated, but also be severely punished; If someone hides grain, once it is found out, it will be dealt with according to the circumstances. Almost half of the grain produced by farmers is delivered by force, and the rest is reserved for seeds, feed and rent. There are not many grains that can really be used as rations. If there is another famine year, farmers will hand over all their rations, seeds and feed, and they will still starve to death after a hard year. 1942 On July 3rd, there was a passage in No.568 of Police Secret issued by the pseudo-Ministry of Public Security: "Due to the serious food shortage in Wangkui County, Bei 'an Province, the people of the county were shrouded in gloomy pessimism ... From May/kloc-0 to 20, more than 30 people committed suicide in Shantou Village of the county. "The Japanese and puppet authorities plundered the grain, and" absolutely gave priority to ensuring military supplies and supplying Japan ". According to records, the amount of grain that Japan asked the puppet Manchukuo to supply was: 65,438+2.2 million tons in 0942; 1943 2.5 million tons; 1944 2.7 million tons; 19453 million tons, increasing year by year, and then supplied to North Korea and North China. As there is little food left, residents "ration" with low standard quotas. Forcibly depress the food consumption of residents to ensure that Japanese imperialism plunders food to the maximum extent. The standard ration of food is low and decreasing year by year. The ration standards of Japanese and Koreans are different from those of southern China. The ration of China people is low in quantity and poor in variety, and it is often interrupted. Hunger among the masses not only caused a serious decline in people's health, but also caused a sharp rise in disease and mortality, which led many residents to commit suicide because of unbearable hunger. According to Jiamusi Japanese Gendarmerie Document No.508, 300 people committed suicide due to lack of food in Heli County, pseudo-Sanjiang Province. In order to meet the needs of the war of aggression, Japanese imperialism also forcibly recruited and apportioned a large number of laborers. According to the survey, during the period of 194 1 year, the Japanese and puppet authorities recruited and used19.53 million people, including injured and dead people, reaching more than 2 million. Japanese imperialism recruits more than 2 million workers from China every year. According to the data of Kwantung Army, the military needed about 400,000 workers in 1942, including 40,000 workers in North China. More than half of the workers were enslaved in important industries that served the war. The Japanese and puppet troops forcibly recruited laborers by cheating or even forcibly capturing prisoners. When transporting workers, load them into stuffy tankers and lock them with iron gates. They are not allowed to go out to eat or sleep. Some workers died before they got off the bus. Once at a station, a worker was driving a stuffy tanker, and the door was locked and put in an idle driveway. Nobody cares for two days. When he opened the door, he was already hungry and cold. When the workers arrive at the workplace, their living conditions are extremely poor. I sleep in a "shack". It is very hot in Leng Xia in winter. In some places, it takes an average of 1 square meter to squeeze four people. The workers were covered with straw bags, sacks and bricks, and curled up their legs to sleep. Mosquito bites in summer are often awakened by freezing in winter. The food is terrible. According to survivors' memories, three bowls of sorghum rice a day with a little pickles, sometimes every meal is gruel or even food-deprived. In the late period of Manchukuo, workers and poor farmers often lived on bran and acorn powder. Under such living conditions, the labor intensity is extraordinary. The average daily working hours are 9 to 10 hours, or even 1 1 hour. There is also a maximum of 14 hours, causing a large number of workers to die from injuries. A Japanese war criminal confessed: "In my memory, the most tragic thing is that about 3,000 workers died in the Daxinganling 1943 urban construction project. "Where the labor force is concentrated,
There are "mass graves" where the bones of China laborers are buried everywhere.
Although it is unlikely that a large-scale war will break out between China and Japan, it is very likely that a small-scale maritime conflict will break out because of the overlap of exclusive economic zones in sea areas and the territorial dispute over Diaoyu Islands, and even a war of the scale similar to the naval battle on Ingerma Island will not be ruled out.
Here is a brief comparison between Chinese and Japanese military forces for reference.
Of course, the army is excluded, because the Chinese and Japanese armies are really incomparable, the difference is too great, and there is almost no possibility of ground conflict.
Japan Air Self-Defense Force:
Japan's main force is 196 F- 15J, which is the Japanese version of F- 15C/E, but it needs to be pointed out that Japan's F- 15J does not have the ability to launch AIM- 120 "advanced medium-range air-to-air missiles".
The 76 F-2 fighters developed by Japan are equivalent to the F- 16 Block50/52 of the United States, with advanced electronic equipment and strong ability to attack the sea.
Nearly a hundred F- 1 fighters are Japanese and American F-4 "ghosts", belonging to old-fashioned aircraft, and their combat effectiveness is not much better than that of the early J-8 in mainland China (the latter J-8 can launch the fourth generation air-to-air missiles).
PLA Air Force:
Su -27/ J-1 1 fighter 183, of which 48 Su-27SK could not launch R-77, and the rest were Su -27SMK.
100 Su -30MKK fighter-bombers, of which 76 Su -30MKK are under the Air Force and 24 Su -30 mkk 2 are under the Naval Air Force, mainly responsible for attacking ships.
By the beginning of 2007, * * was equipped with 100 J-10A/B fighters, and its combat power was equivalent to that of F-16c/D.
At the same time, an unknown number of J-1 1B fighters.
More than 300 J-8 fighters
250-350 JH -7A fighter-bombers
Nearly a thousand J-7 fighters
At the same time, there are four E-767 early warning aircraft in Japan, four Airbus -2000 early warning aircraft in China and an unknown number of electronic scanning radar early warning aircraft in kj-200, which are called "balance beams" by netizens.
Of course, there are hundreds of old-fashioned but modern H -6D bombers in China, but not in Japan. Equipped with long-range anti-ship missiles will pose a great threat to enemy ships.
Below, the "close" weapon:
Japanese F- 15J VS China J-1 1
Japanese F-2 VS China J-10
China Air Police -2000 VS Japanese E-767
In terms of the navy, Japan has the advantage:
Japan has five large air defense ships equipped with Aegis system.
At the same time, it has 5 high-wave class frigates and 9 Murayama class frigates with world advanced level, as well as "Sunward" anti-submarine helicopter carrier and Dayu class amphibious assault ship. Comprehensive combat capability is in the forefront of the world.
China has a huge navy, but not many advanced ships.
Modern destroyers:
There are only two Aegis destroyers of Type 052C, which are inferior to Japanese Aegis destroyers, two 05 1C air defense destroyers, two 052B general destroyers, four Russian "Hyundai" guided missile destroyers, two 052 general destroyers and one 05 1B destroyer, with a total of only 65,438.
Modern frigates include 6 Jiang Wei, 4 Jiang Wei 2, 2 Type 054 stealth frigates and 2 Type 054A stealth frigates.
As for submarines, Japan has 16 advanced conventional submarines, among which "Qinchao" is an advanced AIP submarine.
China has 10 Song-class submarines, two more advanced meta-class submarines, a large number of Ming-class conventional submarines, and four Russian-made Kilo-class conventional submarines known as "ocean black holes" (with the strongest mute performance in the world). China's conventional submarines are not inferior to Japan in quality, but far superior in quantity.
The decisive gap in submarine strength is that China has nuclear submarines, including the latest Type 093 attack nuclear submarine and Type 094 strategic missile nuclear submarine.
Talk about the comparison of military strength under the situation of war;
In terms of air force, Japan has no advantage, because Japan is at an absolute disadvantage in number, but China still has more advanced fighters than Japan in quality. Because the potential conflict area between China and Japan is located in the East China Sea, which is closer to China, China still has a "geographical advantage".
In terms of the navy, Japan has advantages, but it does not mean that Japan must have advantages in naval battles, because the Japanese navy's army-building thinking focuses on air defense and anti-submarine warfare, rather than attacking the sea. Therefore, Japan's Aegis ship has a strong air defense capability, but only eight subsonic anti-ship missiles, while Japan's Murayu and Takabo have strong anti-submarine capabilities, and anti-ship missiles are still only "sufficient" and do not have saturation attack capability.
China's naval air defense and anti-submarine capabilities are far from those of Japan, but it has obvious advantages in attacking the sea. Because the China Navy focuses on attacking maritime targets such as American aircraft carriers, it is equipped with powerful maritime assault firepower:
The main force of the Japanese navy's anti-ship missiles is that each ship is equipped with eight American AGM-84 harpoons, which can only fly at subsonic speed with a range of only 120 km.
In contrast, destroyers such as China 052 and 052b are all equipped with 152 b anti-ship missiles, which have an absolute advantage in firepower density; China's C-602 and C-803 anti-ship missiles have a range of 280 km and 240 km respectively, and the latter terminal penetrates at supersonic speed.
At the same time, the SS-N-22 supersonic anti-ship missile equipped with China's "modern" class guided missile destroyer always flies at 2.5 times the speed of sound, and the interception time is only tens of seconds. Most ship-borne air defense systems in the world have no time to respond. Even a powerful integrated air defense system like Aegis can hardly intercept such a high-speed anti-ship missile, so if four "modern" classes of the East China Sea Fleet volley at the same time,
So imagine the Sino-Japanese naval battle:
China has concentrated the elites of the three major fleets, so China has anti-ship missiles of frigates 051bx16+052x16 = 80c803, 32 SS-N-22 and 052c-602. Attacking the Japanese navy by "saturation attack"-each ship in Murayama and Gao Qiao in Japan has only four fire channels (that is, intercepting four targets at the same time), while Aegis ships can deal with 12- 16 incoming targets at the same time in an absolutely ideal environment, so a Japanese frigate group can intercept at most 30-40 targets (assuming that a single bullet is/kloc-).
On the other hand, the Japanese navy is vulnerable to the attack of China's navy, because the range of Harpoon missile is much smaller than that of China's anti-ship missile, with slow speed and weak penetration ability.
Of course, the above assumptions do not include submarines and aviation. The anti-submarine capability of the Sea of Japan is very strong, so it is difficult for China submarines to approach alone without the cover of the fleet. However, if the fleet provides target instructions and uses submarine-launched missiles to carry out saturation attacks outside its anti-submarine range, one kilogram carrying eight "club" submarine missiles will also have great attack power.
At this time, if Japanese submarines attempt to attack the Chinese fleet, they can only attack with torpedoes because they have no submarine-launched missiles. Although China's anti-submarine capability is weak, it is impossible to face a large number of conventional submarines and nuclear submarines in China.
Coupled with aviation, Su -30MK2+ Flying Leopard +H -6D, if it carries out saturation attack outside the range of its ship-to-air missiles, it can be said that it is completely annihilated-of course, it is not included in the interception range of Japan Air Self-Defense Force. Therefore, if Japan wants to fight a decisive battle with China, its navy can't act alone without the air force, and it must be under the cover of the air force to ensure that it has an advantage in the conflict with China.
Summary:
To sum up, China and Japan are evenly matched in the maritime conflict. The Japanese air force has no advantage over China, while the Japanese navy is superior. However, due to the emphasis on anti-submarine and air defense, while the China navy focuses on anti-ship, the Japanese navy can't take an advantage in naval warfare. In modern warfare, it is impossible for any service to fight alone without other services. If there is a conflict between China and Japan in the future, it will be a decisive battle for the entire air and sea system.
But objectively speaking, the conflict along the coast of China can occupy a considerable advantage in the conflict because the Chinese fleet can get a lot of air support.
