Food Security, Food Prices and Climate Change in China: a Dynamic Panel Data Analysis

This paper provides empirical evidence of the determinants of food security, in which is expressed as a function of various factors, including the per capita disposable income of rural residents, food retail price index, agricultural disaster area, sown area and saving of urban and rural residents, using a dynamic panel data analysis from a sample of 27 provinces over 1985–2007 in China. This paper used POLS, FE (fixed effects), DIF-GMM (difference GMM) and SYS-GMM (system GMM) to estimate the relationship among all the variables. According to the results of SYS-GMM, we found that the climate change will affect the food security significantly in the current year, but food price had no influence on the food security in the current year in China.
