产业融合对中国装备制造业创新效率的影响:结构嵌入的调节作用

从理论和实证两个方面探讨了产业融合对中国装备制造业创新效率的影响，以及网络中心性和网络异质性对二者关系的调节作用。基于2006—2015年省际装备制造7个子行业面板数据，采用ISCNFI指数测度模型和基于产出距离函数的超越对数前沿分析方法，分别测度装备制造业产业融合程度及创新效率变化情况，进而利用面板回归模型对理论假设进行实证检验。结果显示：产业融合程度与中国装备制造业创新效率存在倒“U”型曲线关系，即随着产业融合程度提升，中国装备制造业创新效率呈现出先上升后下降的变化趋势；网络中心性强化了产业融合对装备制造业创新效率的提升作用，而网络异质性削弱了产业融合对装备制造业创新效率的提升作用。

The Impact of Industrial Integration on the Innovation Efficiency of China's Equipment Manufacturing Industry:Adjustment Perspective based on Structural Embedding

This paper discusses the impact of industrial convergence on the innovation efficiency of China's equipment manufacturing industry from both theoretical and empirical aspects,as well as the regulating effect of network centrality and network heterogeneity on the relationship between them.Based on the panel data of 7 sub industries of inter provincial equipment manufacturing from 2006 to 2015,ISCNFI index measurement model and beyond logarithmic frontier analysis method based on output distance function were used to measure the change of industrial integration degree and innovation efficiency of the equipment manufacturing industry respectively,and then the panel regression model was used to test the theoretical hypothesis.The empirical results show that there is an inverted u shaped relationship between the degree of industrial integration and the innovation efficiency of China's equipment manufacturing industry.Network centrality strengthens the role of industrial convergence in improving the innovation efficiency of equipment manufacturing industry,while network heterogeneity weakens the role of industrial convergence in improving the innovation efficiency of equipment manufacturing industry.
