外包的资源配置效应:理论与实证——基于行业要素密度差异视角的研究

Theoretical and Empirical Analysis on Resource Allocation Effects of Outsourcing——Based on the Perspective of Different Intensive of Industry Factors

本文在扩展后的传统贸易模型中,分析了行业要素密度差异视角下外包的资源配置效应。研究发现:外包会加大行业密集要素的使用,资本密集行业的外包会抑制就业、降低工资,劳动密集行业的外包会扩大就业、提高工资。随后构建了动态劳动力需求模型,采用一步广义矩估计法(One Step Diff-GMM),运用美国1 998—2007年投入产出表数据对理论分析结论进行了实证检验。

Using the expanded traditional trade model, this paper analyzes the resource allocation effects of Offshore Outsourcing based on the perspective of different intensive of industry factors. We find that： offshore outsourcing will increase the use of industry-intensive factors, the capital-intensive industry will inhibit employment, lower the level of wages; while the labor-intensive industries will expand employment and raise wages. Then we set a dynamic labor demand model, use one step diff-GMM method to do an empirical test about the theoretical conclusions, using the data of United States＇ input-output table from 1998 to 2007. The research findings have important theoretical value and far-reaching significance for Chinas economic restructuring and the balance between regional developments.
