Empirical Analysis on Influencing Factors of Population Supporting Capacity of Grain Field in Henan Province

This paper firstly reviews the domestic and foreign research on the theory of land supporting capacity. Then combining the existing related research, it empirically analyzes the effect degree and direction of main influencing factors of population supporting capacity of grain field in Henan province by using the muhi-dimensional linear regression method on the basis of the cointegration analysis. The result shows as follows： the factors of population, production technical level of agricultural labor and land affect the population supporting capacity of grain field positively, and the influence of population factor is the biggest ; there is a negative correlation between the factor of grain demand and the population supporting capacity of grain field. Finally, it proposes some policy suggestions in order to enhance the population supporting capacity of grain field in Henan province.
