省域休闲农业发展效率的差异性与收敛性

Differences and convergence of provincial leisure agriculture development efficiency

为了解我国休闲农业发展效率的动态演化特征,利用2008—2016年30个省(市、自治区,统计数据未含西藏自治区及港、澳、台地区,下同)休闲农业数据,将异质性环境变量引入效率测算,利用三阶段DEA对我国休闲农业发展效率进行了测算,并使用PS收敛检验对我国休闲农业效率的收敛性进行了检验。研究发现:1)我国30个省(市、自治区)的休闲农业发展效率存在明显差异,引入环境异质性变量对投入产出变量进行了修正,省际效率差异性更加明显;2)我国休闲农业发展效率整体不存在收敛,但存在俱乐部收敛,有7种收敛类型,不同类型的相对转移路径之间存在较大差异。基于研究结论,提出以下政策建议:转变休闲农业发展方向,从规模扩张向结构升级转变;实施差异化效率提升策略,缩小区域间效率差距;强化区域之间的交流,促进区域休闲农业协作。

In order to understand the dynamic evolution characteristics of China’s leisure agriculture development efficiency,the leisure agriculture data of 30 provinces(municipalities and autonomous regions,the statistical data of Tibet autonomous region,Hong Kong,Macao and Taiwan are not included,the same as below)from 2008 to 2016 were analyzed.Heterogeneous environmental variables were introduced into the efficiency measurement and three-stage DEA was used to evaluate the development efficiency of China’s leisure agriculture.The convergence of the leisure agriculture efficiency in China was verified by PS convergence test.The results showed that:1)There were significant differences in the efficiency of leisure agriculture development in 30 provinces(municipalities and autonomous regions).The introduction of environmental heterogeneity variables has revised the input-output variables,and the differences in inter-provincial efficiency were more obvious;2)There was no convergence in the overall development efficiency of leisure agriculture in China,but there was club convergence effect,and included 7 types of convergence.There were bigger differences between different types of relative transfer paths.The following policy recommendations were proposed based on the research:Transforming the development direction of leisure agriculture from scale expansion to structural upgrading;Implementing differentiated efficiency improvement strategies and narrowing down regional efficiency gaps;Strengthening regional exchanges and promoting regional leisure agriculture collaboration.
