Why are the prices in remote towns low?

First of all, the price you are referring to should have a range. Some commodities have higher prices in big cities, such as agricultural products and some handmade products. Some commodities have the same price, such as salt and gasoline. Some commodities do have lower prices in big cities, such as industrial products produced in large quantities in cities.

In addition to the factors of freight and origin, there is another factor that has to be considered. According to the principle of political economy, all industries in the whole society have a relatively consistent profit rate. The high cost of big cities is caused by housing prices, transportation and other factors. Therefore, in order to ensure the same profit rate, cities must raise the price of goods (because the cost of living is higher than that of small towns), which has caused the phenomenon that some things in big cities have higher prices.

In addition, part of the reason is because of the monopoly or joint monopoly of big cities. As we all know, the goods in supermarkets are generally more expensive than those in convenience stores.

If the above factors are removed, the price of the city is lower than that of the small town as far as the coke you mentioned is concerned. You can imagine Coca-Cola. Its factories are usually in provincial capitals. In the same situation, it is likely that it will be sold cheaper in the city. In a small town, if the income of local residents is not high, it is likely that there will be no market for this kind of cola, and residents will switch to other brands, such as a domestic cola.

There are many factors involved, and it is not easy to fully explain this problem with individual capital.
