区域一体化战略能有效提升创新扩散环节溢出效应吗--以京津冀城市群为例

Can Regional Integration Strategy Effectively Enhance the Spillover Effect of Innovation Diffusion?An Example of the Beijing-Tianjin-Hebei Urban Agglomeration

有效盘活现有科技资源存量,提升区域创新扩散效应,对于确保我国创新驱动发展战略稳步推进、实现高质量发展意义重大。以京津冀城市群为例,重点探究区域一体化战略实施能否有效提升创新扩散环节的空间溢出效应。研究发现,在城市群内部创新资源分布不均衡下,区域一体化战略对提升吸收转化环节溢出效应的影响更显著。其作用机理表现为,区域一体化战略促进区域创新中介主体和知识产权保护主体发育,知识产权保护环境不断优化,使得区域内创新源具备科技成果输出意愿,降低创新策源地与创新腹地之间技术成果交易的信息不对称性,进而提升科技成果的空间溢出效应。同时,当前阶段的区域一体化战略实施尚不能对基础研发投入环节的溢出效应产生显著影响。因此,在区域协同创新难以从基础研发投入环节打开局面的情况下,应该将政策发力点聚焦于科技成果吸收转化环节,尤其应进一步完善知识产权保护体系、优化创新中介发展生态。

In recent years,international trade game is becoming more and more intense with the reshaping of global indus-trial chain and value chain.Technological powers in a technological monopoly position hold key technologies in core fields firmly,while late-developing countries are increasingly difficult and uncertain to obtain innovation achievements through external channels in the process of promoting their own industrial and value chains.Therefore,the key measures to deal with the uncertainty of the current international economic environment are revitalizing the stock of existing domestic tech-nological achievements effectively,activating the vitality of innovation resources,and enhancing the diffusion effect of re-gional innovation,and they are of great significance to ensure the steady progress of China's innovation-driven development strategy and the realization of high-quality development.Therefore this study takes The Beijing-Tianjin-Hebei region as a spatial scope to explore the diffusion effect of region-al innovation at the urban scale.First,the significance of the innovation diffusion effect of Beijing-Tianjin-Hebei urban ag-glomeration is tested by constructing a spatial econometric model covering multiple innovation links such as basic R&D in-vestment,absorption and transformation investment,and innovation achievement output.Secondly,it explores whether the impact of innovation activities in multiple innovation links on regional economic growth has changed significantly before and after the implementation of the regional integration strategy,that is,it verifies whether the impact of innovation input and innovation output on economic growth of cities in urban agglomeration has changed significantly before and after a cer-tain time point from 2012 to 2016 by introducing a structural change model.The study finds that implementing regional integration strategy has a more significant spillover effect on promoting absorption and transformation in the case of imbalanced distribution of innovation resources within urban agglomerations.The internal mech-anism is that the implementation of regional integration strategy effectively promotes the development of innovation intermediaries and intellectual property protection subjects in the region,and the intellectual property protection environment is continuously op-timized,thus enhancing the willingness of innovation sources to export scientific and technological achievements in the re-gion.The innovation intermediary subject can reduce the information asymmetry between the source of innovation and the hinterland of innovation to a certain extent,thus effectively promoting the trade and promotion of scientific and technologi-cal achievements.At the same time,it is also found that the implementation of regional integration strategy in the current stage cannot have a significant impact on the spillover effect of basic R&D investment.The implication is that policy should be focused on the absorption and conversion of scientific and technological achievements,especially to further opti-mize the intellectual property protection system and improve the innovation intermediary development ecology in the case that regional collaborative innovation is difficult to make from the basic R&D input.On this basis,this study draws the following policy implications.The governments should strengthen the matching efficiency between the research and development end and the demand end,improve the construction of the intellectual property value evalua-tion system,and promote the efficiency of the transformation of scientific and technological achievements.Starting from the de-mand side,this study conducts in-depth research on the industrial development needs of Tianjin and Hebei,and explores the direc-tion of the connection between the industrial chain and the innovation chain.As sources of innovation,Beijing's science and tech-nology authorities,leading enterprises,academic research departments and R&D institutions should form relevant teams to con-duct discussions and research on high-tech industry sectors in Tianjin and Hebei,look for subdivided industry sectors that have the ability to integrate and connect with Beijing's scientific and technological resources with the actual needs of indus-trial development,and gradually establish docking"nodes".Then,they should rely on the docking nodes to realize the deep integration of industrial chain and innovation chain.Starting from the supply side,the study explores the application scenarios of Beijing's science and technology innovation resources in Tianjing and Hebei.Governments of Beijing,Tianjin and Hebei should focus on scenario-driven in Tianjin and Hebei,fully tap the potential value of intellectual property,and build a scientific multi-dimensional evaluation index system for intellectual property value of scientific and technological a-chievements,so as to make more scientific and technological achievements in Beijing(the source of innovation)applied to Tianjin and Hebei(the places where innovation is undertaken).
