Abstract:

Food is the first necessity of mankind. Technological progress is an important means to ensure the increase of food production, quality improvement and security. In order to investigate the important role of technological progress in food production in China, this paper analyzes the technological progress pace and contribution rate to japonica rice production based on the provincial panel data of 12 provinces from 1985 to 2013. The paper adopts the improved multi-element level CES production function. The results show that the technological progress pace is 0.44% and its contribution to japonica rice production in China from 1985 to 2013 reaches 33.13%. Related agricultural policies made by the government based on specific conditions in different periods have a major influence on the technological progress pace and its contribution to japonica rice production. Since the eastern, central and western regions of China are quite different from each other in natural and socio-economic environment, their respective technological progress pace and its contribution to japonica rice production are also significantly different in space. Finally, this paper puts forward some policy recommendations for promoting the japonica rice production.

Key words: japonica rice production, technological progress pace, contribution rate, spatial difference
