Office supplies are infrastructure or administrative expenses in the state-funded projects. Research funds from state-funded projects are mainly used to support scientific research activities, such as the purchase of experimental equipment, consumables, laboratory rental, travel expenses and other expenses directly related to research work. Office supplies are mainly necessary expenses to ensure the normal operation of the office, such as tables and chairs, computers, printers, paper, notebooks, etc. Therefore, for research funds for state-funded projects, the budget for office supplies is usually listed separately and is not included in the scope of research funds.
