生产性服务业对制造业效率的影响研究——基于产业创新视角的实证分析

The Effect of Producer Services on Manufacturing Efficiency——An Empirical Analysis from the Perspective of Industrial Innovations

生产性服务业与制造业发展的相互关系一直是学界关注的热点问题。文章基于中国东部省区2005～2012年的面板数据．通过构建计量模型，实证研究了生产性服务业的技术创新、组织创新和制度创新对制造业效率增长的影响。研究结果表明：总体上生产性服务业的创新发展对制造业效率增长具有显著的正向影响，其中技术创新和组织创新的影响相对更为显著。值得注意的是，代表生产性服务业制度创新能力的市场化指数与制造业效率增长负相关，这与预期结果不符，文章对此给出了可能的解释。最后提出了相关政策建议。

The relationship between producer services and manufacturing is always a hot issue in academic field. Based on panel data of eastem provinces of China from 2005 to 2012 and through construing an empirical model, the article analysed the effects of technological innovation, organizational innovation and institutional innovation of producer services on manufacturing efficiency. Results show that, in general, innovations of producer services have significant and positive effects on manufacturing efficiency, and the effects of technological innovation and organizational innovation are relatively bigger. However, it is worth noting that the marketization index which represents institutional innovation of producer services has a negative effect on manufacturing efficiency. This is out of the expectation. The article offered possible explanation for this phenomenon and also proposed some policy suggestions.
