摘要: 运用EBM-Super-Malmquist指数法对2004—2018年玉米主产省(市、自治区)的生态效率进行测算,分析玉米生态效率的时间演变和地区分布特征,并运用收敛性方法检验玉米生态效率的收敛性。结果表明,玉米生态效率表现出波动下降趋势,地区之间存在明显的非均衡性特征;全国及四大区域玉米生态效率不存在σ收敛和绝对β收敛,地区差异不会无条件地缩小;全国及四大区域玉米生态效率存在显著的条件β收敛,受灾率、财政支持力度、人力资本是影响玉米生态效率条件β收敛的重要因素。

Abstract: Maize eco-efficiency of the main producing provinces (cities and autonomous regions) from 2004 to 2018 was calculated by the EBM-Super-Malmquist index method, the temporal evolution and spatial distribution characteristics of maize eco-efficiency were analyzed, and the convergence of maize eco-efficiency was tested by the convergence method. The results showed that, maize eco-efficiency showed a fluctuating downward trend, and there were obvious characteristics of imbalance between regions. There were no σ convergence and absolute β convergence in maize eco-efficiency across the country and the four major regions, and regional differences would not be unconditionally narrowed. There were significant condition β convergence for maize eco-efficiency across the country and the four major regions. Disaster rate, financial support and human capital were important factors that affected β convergence of maize eco-efficiency condition.

Key words: maize, eco-efficiency, EBM-Super-Malmquist index, temporal and spatial differences, convergence
