三大城市群要素流动效率及差异性评价分析!

Evaluation of the Factor Flow Efficiency and Discrepancies among Three Urban Agglomerations

生产要素的流动性是资源有效配置的前提,要素流动是通过改变要素之间的比例来影响资源配置效率,因此,要素流动的效率体现在流动和资源配置两个阶段。通过建立两阶段DEA模型测算2009~2014年三大城市群38个城市的要素流动效率,结果发现:2009~2014年三大城市群要素流动程度均提高了,且要素流动的结构发生了明显的变化,大部分城市资本流动比重由大变小,技术流动比重越来越大;流动阶段效率偏低,单纯的提高流动程度已经不能提高要素流动效率,应调整其流动结构;资源配置阶段的效率优于流动阶段的效率,且第二阶段的综合效率在2009~2014年是稳步提升的。

The mobility of production factor is the premise for effective allocation of resources.Factor flow affects the efficiency of resource allocation by changing the proportion of a factor,which is reflected in two phases,factor flow and resources allocation.By using two-stage DEA model,this article measured efficiency of factor flow of the three urban agglomerations,including 38 cities from 2009 to 2014.The results showed that the degree of factor flow of three urban agglomerations increased from 2009 to 2014,and the structure of the factor flow index had changed obviously.In most cities,the proportion of capital flow declined,and the proportion of technical flow steadily increased.The efficiency of the flow stage was low.The factor flow efficiency was not improved when merely the degree of mobility was increased.The flow structure should have been adjusted.The efficiency of resource allocation was better than that of the flow stage.The efficiency of the second phase was steadily improved from 2009 to 2014.
