农业生产效率、收敛性与气候变化——以广西为例

Agricultural Production Efficiency, Convergence and Climate Change: Taking Guangxi as an Example

基于广西各地级市2006—2014年的面板数据,运用Malmquist-DEA方法测度广西各地区的农业生产效率并分析了其收敛情况,利用线性回归的方法研究了气候变化对广西全区及5大经济区域农业生产效率的影响。结果发现:全区年际全要素生产率年均下降0.9%,但呈现出先下降后上升趋势;农业生产效率存在收敛的趋势;总体上看,近年的气候变化对农业生产效率有负面影响。

Based on the panel data of cities in Guangxi province in 2006-2014, this paper measures the agricultural production efficiency of Guangxi province by using the Malmquist DEA method, then it analyzes its convergence. Linear regression method was used to study the impact of climate change to agricultural production efficiency in Guangxi province and 5 economic regions. The results showed as follows： Total factor productivity fell by an annual rate of 0.9%, but it present a first rise after falling; Agricultural production efficiency showed the trend of convergence. On the whole, recent climate change has a negative effect on the agricultural production efficiency.
