摘要 将创新型城市建设视为一项“准自然”实验,基于2008—2021年中国272个地级及以上城市面板数据,应用多时点双重差分模型考察创新型城市建设对数字全球价值链参与的影响。研究发现:整体来看,创新型城市建设可提升数字全球价值链参与水平,这一结果在经过一系列稳健性检验后依然成立。异质性检验结果表明,创新型城市建设对中小规模、沿海区域及低市场化程度城市参与数字全球价值链的作用效果更为显著。作用机制检验结果表明,创新型城市建设主要通过缓解要素结构错配、前沿数字技术追赶以及服务贸易结构升级对数字全球价值链参与产生推动作用。基于上述结论,提出全面深化创新型城市战略点布局、推动城际数字经济联动格局建设、统筹构建城际数据统一要素市场的政策建议,为高水平建设创新型城市,提升国际数字价值链地位提供新思路。

Abstract: Taking the innovative city construction as a “quasi-natural” experiment, and based on the panel data of 272 cities at prefecture level and above in China from 2008 to 2021, this paper applies the multi-time point double difference model to investigate the impact of innovative city construction on digital global value chain participation. The study finds that innovative urban construction can improve the participation level of digital global value chain as a whole. This result is still valid after a series of robustness tests. The heterogeneity test results indicate that the construction of innovative cities has a more significant effect on the participation of small and medium-sized, coastal areas and low marketization cities in the digital global value chain. The results of further mechanism test show that the construction of innovative cities promotes the participation of digital global value chain mainly by alleviating the mismatch of factor structure, catching up with cutting-edge digital technology and upgrading the structure of service trade. Based on the above conclusions, innovative policy suggestions are proposed to comprehensively deepen the layout of innovative city strategic points, promote the construction of intercity digital economy linkage pattern, and coordinate the construction of data unified factor market between cities, so as to provide new ideas for high-level construction of innovative cities and enhance the position of the international digital value chain.
