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:

Given insufficient efficiency areas of industrial park land in China,we selected 16 state-level industrial parks in the Yangtze River delta urban agglomeration. Based on the input and output unit land area index,VRS-DEA modeling and the Malmquist index,we decompose the dynamic evaluation of land use efficiency,and analyze the input and output factors of improving potential. We found that from 2010-2014,the Yangtze River delta urban agglomerations industrial park comprehensive efficiency of land use was an average of 0.600. Only two industrial parks are efficient,and the efficiency differences between land use regions is obvious. In the view of changes in efficiency decomposition,changes in the scale efficiency of land use are the main cause resulting in the evolution of technical efficiency. From a dynamic time series,the Malmquist productivity index was driven by technical efficiency change and grew over the five years. Weakness in technical improvements is the core element of land use efficiency. Through the analysis of land use non-DEA efficient urban spaces,industrial parks have common output redundancy including tax revenues and industrial production. While maintaining investment scale effectiveness,improving the technical efficiency of industry,investment promotion and the tax system is a realistic path to improve land use efficiency of industrial parks in Yangtze River Urban Agglomerations.
