电子及通讯设备制造业集聚对其全要素生产率影响研究

Research on the Impact of Electronics and Telecommunication Equipment Manufacturing Agglomeration on Its Total Factor Productivity

基于2009~2015年的中国省级面板数据,使用DEA-Malmquist指数测算电子及通讯设备制造业的全要素生产率,研究了电子及通讯设备制造业集聚对其全要素生产率的影响。研究结果表明:电子及通讯设备制造业的专业化集聚与其全要素生产率之间呈倒"U"型关系,最优的专业化集聚规模在0.7左右,控制变量的加入会导致最优的专业化集聚规模产生小范围的波动,但结果维持在0.7~0.75之间;将全要素生产率分解为技术进步(TECHCH),纯技术效率(PECH)和规模效率(SECH)之后,三项对全要素生产率的影响都显著为正,就影响程度来看规模效率>技术进步>纯技术效率。

Based on China＇s provincial panel data from 2009 to 2015, the DEA-Malmquist index was used to measure total factorproductivity of the electronics and communication equipment manufacturing industry. Impact of the manufacturing concentration ofelectronics and communications equipment on its total factor productivity was studied. The conclusions of this paper are as follows： there is a significant inverse U-shaped relationship between the specialized agglomeration of electronics and communicationsequipment manufacturing and its total factor productivity. The addition of control variables will lead small-scale fluctuations to theoptimal specialization. The result was between 0.7 and 0.75. After factoring the total factor productivity into TECHCH, PECH andSECH, the impact of the three on total factor productivity was significantly positive. SECH〉TECHCH〉PECH in terms of impact.
