中国制造业国际外包与能源利用效率研究

International Outsourcing and Energy Use Efficiency of Manufacturing Industries in China

文章使用1992年至2002年的投入产出表数据计算出中国14个制造业行业的国际服务和实物外包水平,通过面板数据方法检验了国际外包对制造业能源利用效率的影响。实证结果发现国际服务和实物外包与能源利用效率呈"U"型关系,国际外包达到一定水平后将会对能源利用效率产生正面的作用,并且对不同行业能源利用效率的影响存在差异。从长期看,国际外包对提高制造业行业的能源利用效率具有正向作用,这意味着我国需要进一步推进国际外包活动。

Using the data of input-output tables from 1992 to 2002, the paper calculates the international service and material outsourcing level of fourteen manufacturing industries and tests the effect of international service and material outsourcing on energy use efficiency. Empirical results indicate that the relationship between international service and energy use efficiency is featured by U-type, and it is the same as the relationship between material outsourcing and energy use efficiency. When international service reaches certain levels, it will positively affect energy use efficiency, and its effects vary in different industries. In the long run, international outsourcing has positive effects on improving energy use efficiency, so the governments should advance the international outsourcing activities further.
