Spatio-Temporal Evolution and Regional Difference Analysis of China’s Agricultural Technology Progress Under Two-Way Output

Abstract

Studying the spatio-temporal evolution and regional differenhengces of China’s agricultural technological progress is of great significance for the rational formulation of agricultural carbon emission reduction policies. Based on the panel data of 31 provinces and cities in China from 2006 to 2016, the total factor productivity of agriculture is measured by DEA-Malmquist index. The change trend of total factor productivity of agriculture and its four decomposition indexes are analyzed and investigated, and the spatial difference is also investigated. It is found that the total factor productivity fluctuates periodically and the regional imbalance is obvious. Some suggestions are put forward, such as improving the efficiency of resource utilization, optimizing the structure of agricultural industry, and enhancing technology spillover through regional cooperation, so as to provide reference for the overall emission reduction in the country.
