信息基础设施建设与关键核心技术创新
Information Infrastructure Construction and Key Core Technology Innovation
摘要
Abstract
Against the backdrop of pursuing technological self-reliance and the restructuring of global value chains,breaking through bottleneck technologies and achieving breakthroughs in key core technologies have become strategic pillars for national development.Can the development of information infrastructure serve as a breakthrough strategy for enterprises'key core technology innovation(KCTI)?Drawing upon innovation-driven theory,technolo-gy convergence theory,and network externalities theory,this paper explores the impact of information infrastructure development on enterprises'KCTI and its underlying mechanisms.The study reveals the operational mechanisms through which information infrastructure development influences corporate innovation across three dimensions:mac-ro-level intra-city technology integration effects,inter-city collaborative innovation effects,and micro-level corpo-rate digital transformation effects. Using data from Chinese cities and manufacturing listed companies from 2012 to 2023,this study empirically examines the impact of urban information infrastructure development on KCTI of enterprises.Findings indicate that,after a series of robustness tests,information infrastructure development significantly drives KCTI of enterprises.Mechanism tests reveal that this impact occurs through macro-level intra-city technological integration effects,inter-city collaborative innovation effects,and micro-level corporate digital transformation effects.Heterogeneity analysis reveals that the promotional effect of information infrastructure development on KCTI of enterprises is pronounced in central China,cities with lower economic development,asset-intensive industries,and large,densely distributed enterprise clusters.Further analysis indicates that digital product innovation and digital process innovation exhibit a more pronounced promotional effect through information infrastructure development,with differing performance be-tween high-and low-scoring groups. The policy implications are as follows.First,it should persistently advance the construction of new information infrastructure.Strategic investments in new infrastructure should be increased to optimize network coverage quality and computing power supply.Second,it should focus on building an"integrated-collaborative"innovation ecosys-tem,actively guiding multidimensional technological convergence within cities.Third,the government should strengthen targeted support for enterprise digital transformation.It should employ a combination of policies to help SMEs overcome transformation barriers and fully unleash the enabling potential of information infrastructure for in-novation processes.Fourth,it should implement inclusive yet differentiated support strategies.Infrastructure devel-opment and policy assistance should moderately favor central and western regions,areas with lower industrial densi-ty,and enterprises with weaker absorption capacity,and prioritize support for digital product and process innovation to narrow the"digital divide"and extend innovation dividends to more market entities.关键词
