我国制造业不同外包形式的就业效应研究——基于动态劳动需求模型的实证检验

A Study on the Employment Effects of the Manufacture’s Different Outsourcing——Based on a Dynamic Labor Demand Model

本文测算了我国27个制造业细分产业的总外包水平、低技术外包水平、高技术外包水平和服务外包水平,并构建了我国制造业的动态劳动力需求模型,利用一步广义距估计(One Step Diff-GMM)法分析了制造业的总体外包、低技术外包、高技术外包和服务外包的就业效应,结论为:制造业总体外包、低技术外包和高技术外包对就业呈抑制作用;低技术外包和高技术外包水平相当,但低技术外包的就业净效应是高技术外包的将近二倍;而服务外包规模尚小,还不足以对就业产生影响。

This paper measured the level of overall outsourcing, low-tech outsourcing, high-tech outsourcing, and service outsourcing of our country＇s 27 segments of manufacture, and set a dynamic labor demand model, then used one step diff-GMM method to test the employment effects of the manufacture＇s overall outsourcing, low- tech outsourcing, high-tech outsourcing and service outsoureing. The result showed that： The overall outsourcing, low-tech outsourcing and high-tech outsourcing had restrain effects to employment; The level of low-tech outsourcing was similar to high-tech outsourcing, but it was more then twice its restrain effects; The scale of service outsourcing is small, had no effects to the manufacture＇s employment.
