摘要:

产业分工联系是区域一体化的基础,但已有产业技术关联的文献主要关注区域内部,缺乏对跨区域产业技术关联的探究。由于中国省际产业联系数据难以获取,论文运用引力模型和交叉熵法,基于2002、2007、2012年30省的投入产出表拟合出省际产业贸易流量矩阵,并进一步计算跨区域产业技术关联指数。跨区域产业技术关联呈现不断加强的趋势,尤其是城市群内部各地区产业之间的联系。基于2002、2007、2012年中国30个省16个制造业部门的面板数据,使用固定效应模型进一步考察了跨区域产业技术关联对产业创新的影响。结果发现,跨区域产业技术关联有利于区域产业创新,但在本地产业技术联系较强的地区,跨区域产业技术关联对产业创新的正效应会被削弱,本地产业技术关联和省际产业技术关联之间存在“替代效应”,知识产权的地方保护主义是导致这一结果的可能原因。因此,政策上应倡导扫清制度障碍、完善知识产权保护制度,促进跨区域产业对本地的技术溢出,进一步推动区域产业创新。

Abstract:

Geographic proximity arising from industrial agglomeration can promote firm innovation and thereby industrial development. Scholars of evolutionary economic geography further propose that technology proximity is more important than geographic proximity, which provides essential theoretical support for explaining the role of interregional industrial linkages in local industrial development. However, the existing literature mainly focuses on the technological relatedness within regions but lacks research for interregional relatedness, especially the effects of interregional technology relatedness on regional innovation. Based on the input-output panel data of 2002, 2007, and 2012 from 30 provinces of the mainland of China, this study used the gravity model and cross-entropy method to fit the interprovincial trade flow matrix of the industries and further computed the index of intraregional and interregional technological relatedness. This study then used a two-way fixed effect model to examine the effects of intraregional and interregional technological relatedness on industrial innovation based on the data of 16 manufacturing sectors in 30 provinces in 2002, 2007, and 2012. First, the results show that the degree of interregional technological relatedness of industries has been strengthened, especially the linkages within city agglomerations. Second, interregional technological relatedness of industries has a positive effect on industrial innovation, but local technological relatedness of industries would weaken this positive effect. Therefore, the government should remove institutional barriers and encourage the inter- or intraregional industrial linkages that promote regional industrial innovation.

Key words: technological relatedness, intraregional relatedness, cross-regional relatedness, regional industrial innovation, input-output
