摘要
利用2010—2020年京津冀地区城市面板数据,采用双向固定效应模型、门槛效应模型,考察北京作为中心城市对周边城市创新能力提升的引领效应。研究发现,北京创新能力强于周边城市,对周边城市具有正向创新引领效应;异质性分析表明,北京对规模较大城市、国家创新型试点城市、沿海城市、高行政等级城市的创新引领效应更显著;机制分析表明,北京通过企业研发、专利申请和技术平台对周边城市产生正向创新引领效应;门槛效应分析发现,北京对周边城市的创新引领效应受到技术距离的影响,当技术距离小于门槛值时,北京的创新引领效应较显著,反之则较弱。
The Beijing-Tianjin-Hebei regions have played an important role in driving the high-quality regional development.However,for a long time,Beijing,as a central city,has failed to play a role of innovation leader,and the gap between Beijing and its neighboring cities in innovation development has been further widened,which has posed a major challenge for realizing the collaborative regional development.Therefore,it is of practical significance to make better use of the innovation leadership effect of Beijing and improve the innovation capability of the surrounding cities for the collaborative innovation development of Beijing,Tianjin and Hebei.Drawing on the panel data of the Beijing-Tianjin-Hebei regions from 2010 to 2020,this paper systematically studies the innovation leadership effect of Beijing on its neighboring cities by using the two-way fixed-effect model and threshold effect model.It is found that the innovation capability of Beijing is far higher than that of the surrounding cities,and the innovation leadership effect significantly improves the innovation capability of the surrounding cities.Heterogeneity analysis shows that innovation leadership of Beijing has a strong effect on megacities and big cities in the Beijing-Tianjin-Hebei regions,national innovation pilot cities,coastal cities and cities with high administrative levels,for these cities tend to better play the role of innovation leadership and keep improving their innovation capabilities.The mechanism analysis shows that enterprise R&D,patent application and technology platform are important mechanisms for innovation leadership effect of Beijing to improve the innovation capability of surrounding cities,and the surrounding cities can focus on enterprise R&D,patent application and technology platform to carry out more extensive and deeper innovation cooperation with Beijing.The threshold effect analysis shows that the innovation leadership effect of Beijing on its neighboring cities has a nonlinear relationship and is affected by the threshold value of technological distance.When the technological distance is below the threshold value,the innovation leadership effect of Beijing is stronger,and Tianjin and Shijiazhuang are the cities in this range;otherwise,the innovation leadership effect of Beijing will be weakened.Cities in this range include Baoding,Tangshan,Langfang,Cangzhou,Xingtai,Handan,Qinhuangdao,Hengshui,Zhangjiakou and Chengde.The research conclusions suggest that first it is critical to improve the policy design of innovation leadership in Beijing from a strategic perspective and enhance the innovation capability of Beijing.It is essential to closely integrate major national strategies such as the regional coordinated development strategy and the Beijing-Tianjin-Hebei coordinated development strategy,high-quality innovation resources with the formulation of Beijing's innovation leadership policies to further promote the construction of the Beijing-Tianjin-Hebei collaborative innovation community.Second,large cities in the Beijing-Tianjin-Hebei regions,national innovative pilot cities,coastal cities and cities with high administrative levels should formulate policies and take measures to further enhance innovation capability and improve innovation quality,and while other cities should give full play to their latecomer advantages,increase the investment in scientific research funds,create an innovation policy environment conducive to attracting talents,capital and innovative enterprises,and comprehensively improve urban innovation capacity.Third,it is necessary to give full play to the institutional role of corporate R&D,patent cooperation and technology platforms in Beijing's innovation leadership.Neighboring cities should formulate tax relief policies to encourage corporate R&D,strengthen cooperation and exchanges with relevant research institutions in Beijing,and provide preferential funds for technology development,transfer,consultation and service to speed up the construction of technology platform system and personnel training.Fourth,in order to shorten the technological distance with Beijing,the cities with strong technological capabilities should formulate strategic plans for the development of cutting-edge technologies,and set up special funds to support technical cooperation.For the cities with weak technological capabilities,they should increase the policy support in the introduction and training of technical talents,capital investment and other aspects,expand the channels of information collection,and formulate a reward system.With the focus on the influence of the innovation leadership effect of the central city on the innovation capability of surrounding cities,this paper provides the corresponding influence mechanism which is a useful supplement for related research.
