Abstract:Based on the application of gravity center model,this paper described the space-time evolution path of the gravity center of agricultural economic and agricultural factor endowment structure in China from 1978 to 2015.Meanwhile,it measured the agricultural economy by coupling the process of spatial changes of the gravity center of endowment structure.The research results showed that:(1) The gravity center of agricultural economy in China exhibited a relatively stable macroeconomic trend,shifting from east to northwest on a small scale in the recent forty years.(2) The gravity center of the labor in agriculture moved northwest; the gravity center of agricultural capital,besides moving to the west firstly and then to the east,showed the trend of moving to the north; the gravity center of per capital generally showed an inversed S pattern to the northeast.(3) The shift of gravity center of China’s agricultural economy in the eastwest direction was mainly caused by the shift in the gravity center of the labor.The shift in the gravity center of agricultural capital has led to the shift of gravity center of the agricultural economy in the north-south direction.
