第二产业生产服务与第二产业生产率——基于面板数据的实证研究

Production Service of Secondary Industry and Productivity of Secondary Industry——An Empirical Study Based on Panel Data

根据OECD发布的24个国家投入产出表,分别计算了1995年、2000年和2005年各国第二产业的劳动生产率,采用面板数据模型检验了第二产业生产服务对第二产业生产率,以及对第二产业就业和产出的影响。检验结果表明,当服务投入在第二产业总产出中所占比重不断提高时,第二产业劳动生产率将随之提高,并不会减少第二产业就业人数。因此,第二产业生产服务对第二产业产出有显著的促进作用。

Based on input-output tables of 24 countries issued by OECD,this paper calculates productivity of labor in secondary industry of each country in 1995,2000 and 2005 respectively,using panel data model estimates the effects of production service of secondary industry on productivity,employment and output of secondary industry.The result shows that when the proportion of service in the total output of secondary industry constantly increases,the productivity of secondary industry accordingly increases,which has no negative effect on employment of secondary industry.Therefore,production service of secondary industry has remarkable effects on promoting the output of secondary industry.
