Grain Science and Technology Policies and Food Security in China: An Empirical Study Based on a Provincial Dynamic Panel Model

Abstract

Abstract China’s grain science and technology policies have played an important role in the development of China’s food industry. This paper aims to examine the effects of China’s grain science and technology policies on food security. It quantitatively assesses China’s food security by analyzing the main contents and development trends of China’s food science technology policies through the text metrology method, and then investigates the effects of grain science and technology policies on food security by employing a provincial dynamic panel model. The results show that food security in China is all-round developed, and that the release frequency and cumulative effect of grain science and technology policies play a significant role in promoting food security. Powerful grain science and technology policies can effectively guarantee China’s food security.
