在利用成本费用利用率和增加值率对长三角16个核心城市工业企业的投入产出效率进行测度评价以及运用区位商和摩尔结构转换值对长三角的产业分工、产业结构变动进行衡量的基础上,建立面板数据模型揭示长三角工业企业的成本费用利用率与产业结构变动之间的内在关联。结果显示:长三角地区存在低成本费用利用率现象,但这并未构成对长三角产业结构升级和产业发展的倒推力;一定程度的产业同构能够促使生产要素流向边际生产率高和比较利益高的行业或企业,从而有助于产业的合理分工、集聚和产业结构的升级。
In the use of cost and utilization efficiency and value added rate of the Yangtze River Delta in 16 core cities of industrial enterprises to measure the efficiency of input-output and the use of location quotient and the value of the molar structure of the Yangtze River Delta industrial division of labor, the basis for measuring changes in industrial structure On the establishment of panel data model to reveal the Yangtze River Delta industrial enterprises cost-benefit ratio and the inherent correlation between changes in industrial structure. The results show that there is a low cost utilization rate in the Yangtze River Delta region, but this does not constitute a re-pushing force for industrial structural upgrading and industrial development in the Yangtze River Delta. To a certain extent, industrial isomorphism can promote the flow of production factors to high marginal productivity and high comparative benefits Industry or business, thus contributing to the rational division of labor industry, concentration and upgrading of industrial structure.
