Second, achieve coordinated development of national defense and economic construction, and adapt the national defense and military development strategies to the national development strategy. Military modernization needs a lot of investment, and China has limited financial resources. It is a correct choice based on the overall development of China to maintain a moderate increase in defense expenditure and an appropriate proportion. Through scientific development planning and planning, national defense and army building should be brought into the strategic overall situation of national modernization, so that the process of national defense and army modernization is consistent with the process of national modernization. In the case that the contradiction between the demand and funds for national defense and army modernization will exist for a long time, we must unswervingly follow the road of national defense and army modernization with less investment and high efficiency according to the requirements of Scientific Outlook on Development, further unify the quality and efficiency, and make national defense and army construction develop continuously on the basis of increasing national financial resources.
