装备制造业技术进步的溢出效应——基于两部门模型的实证研究

The Spillover Effects of Technological Progress in the Equipment Manufacturing Industry:A Empirical Research Based on a Two-sector Model

本文将整个工业分为装备制造和非装备制造两类部门，把装备制造业技术进步纳入非装备制造部门的生产函数中，通过构建两部门模型研究装备制造业技术进步与其他工业部门产出增长之间的关系，并以2000--2007年我国31个省区的面板数据为样本进行了实证检验，得到装备制造业技术进步对非装备制造部门存在显著的溢出效应的结论，不同区域分组的估计结果说明装备制造业自身的生产效率和非装备制造部门的设备更新速度对技术溢出效应具有显著影响。

In this paper a manufacture industry is divided into an equipment sector and a non-equipment sector. The technological progress of the equipment sector is added to the production function of the non-equipment sector. Our empirical study uses a panel data set from 31 Chinese provinces for the period 2000--2007. We find that there are significant spillover effects of the technological progress of the equipment sector on the non-equipment sector. The production efficiency of the equipment sector and the equipment upgrading cycle of the non equipment sector significantly influence the spillover e{{eets.
