知识密集型服务业与制造业企业全要素生产率——基于中国工业企业数据的经验分析

The Influence of Knowledge-intensive Services on Total Factor Productivity of China Manufacturing Industry——An Empirical Analysis based on China's Industrial Enterprises Database

文章分析了知识密集型服务业发展提升制造业生产效率的内在机理,并运用2003-2007年中国工业企业数据对知识密集型服务业对制造业企业全要素生产率的影响进行了实证检验。研究结果表明:我国知识密集型服务业发展与制造业企业全要素生产率具有显著正相关性;东部地区知识密集型服务业对全要素生产率提升产生显著的积极影响,但是中部和西部地区知识密集型服务业专业化程度的提高反而会阻碍企业全要素生产率提升;知识密集型服务业对劳动密集型制造业企业生产效率的提升作用更加明显,对资本密集型和技术密集型制造业企业生产效率的影响相对较小。

The paper explores the impact effects of Knowledge-intensive Services （KIS） on the total factor productivity （TFP） ofindustrial enterprises in China, and tests the influence of KIS on TFP by using 2003-2007 Chinese large and medium-sized industrialenterprises panel data. The results show that：the effect of knowledge-intensive Services on industrial enterprises in TFP is positivesignificant; from the regional perspective,the TFP of industrial enterprises is positively related with KIS in eastern area of China whilenegatively influenced by KIS in central and western areas. the research results also show that the effect of KIS also has different impactson TFP among different technological levels of industrial enterprises,which means KIS have relatively stronger positive effect on laborintensiveenterprises than on capital-intensive and technology-intensive ones. Therefor,this research suggests reasonable strategy andpolicy should be implemented based on different regional and technological level.
