【摘要】：针对长三角城市群工业园区动态效率研究不足的问题,本文选取16个国家级工业园区为研究样本,基于单位土地面积投入产出指标,利用VRS-DEA模型与Malmquist指数,对2010-2014年长三角城市群工业园区土地利用效率情况进行分解动态评价,并定量分析其投入产出要素改善潜力。研究发现:(1)长三角城市群工业园区在5年间的土地利用综合效率均值为0.600,仅2个工业园区在5年中均DEA有效,且地域差异明显,从效率分解变化来看,规模效率纯技术效率技术效率;(2)从动态时间序列看,5年间工业园区Malmquist生产率指数整体呈增长趋势,技术效率变化贡献最大、纯技术效率变化贡献其次,而技术进步变化拖累,说明技术改进的薄弱是影响工业园区土地利用效率的核心因素;(3)通过对5年间土地利用DEA无效工业园区的要素投入产出改善途径与潜力分析,发现以税收收入与工业产值不足为核心的有效产出不足为各工业园区DEA无效的主要原因,长三角城市群各工业园区应在保持投入规模有效性的基础上,提升工业技术效率,同时完善转型升级期间工业园区招商引资与税收制度。
[Abstract]:In order to solve the problem of insufficient research on dynamic efficiency of urban agglomeration industrial parks in Yangtze River Delta, this paper selects 16 national industrial parks as research samples, based on the input-output index of unit land area, using VRS-DEA model and Malmquist index. The land use efficiency of Yangtze River Delta urban agglomeration industrial park from 2010 to 2014 is evaluated dynamically. It is found that the average comprehensive land use efficiency of the Yangtze River Delta urban agglomeration industrial park in five years is 0.600, and only two industrial parks are effective in 5 years, and the regional differences are obvious. From the point of view of efficiency decomposition, scale efficiency, pure technical efficiency, technical efficiency, from the dynamic time series, the Malmquist productivity index of industrial parks as a whole shows an increasing trend during the past five years. The change of technical efficiency contributes the most, followed by the change of pure technical efficiency. The change of technological progress is a drag, indicating that the weakness of technological improvement is the core factor affecting the efficiency of land use in industrial parks. Through the analysis of the ways and potential of improving the input and output of the factors in the ineffective industrial parks of land use DEA in the past five years, It is found that the main reason for the invalidation of DEA in the industrial parks is the insufficiency of effective output with the lack of tax revenue and industrial output value. The industrial parks of the Yangtze River Delta urban agglomeration should improve the efficiency of industrial technology on the basis of maintaining the efficiency of input scale. At the same time, improve the transformation and upgrading of industrial park investment and tax system.
