Abstract

The implementation of the innovative city pilot policy (ICPP) is conducive to promoting the urban industry–university–research collaborative innovation, but there is no clear answer to how industry–university–research knowledge flow is affected by the policy. Based on the knowledge flow process divided into the knowledge creation stage and knowledge transfer stage, this paper uses the two-stage Data Envelopment Analysis (DEA) model to measure the dual efficiency of urban industry–university–research knowledge creation and knowledge transfer. And the paper also adopts the spatial difference-in-difference (SDID) model to study the impact mechanism of ICPP on the knowledge flow dual efficiency. The results show that there are positive spatial spillover effect of the knowledge creation efficiency (KCE) and knowledge transfer efficiency (KTE). And the effects of ICPP on industry–university–research KCE and KTE are both manifested as the promoting impact. Furthermore, ICPP has a significantly positive impact on the urban innovation atmosphere (UIA), and UIA plays a partial mediating role in the impact mechanism of ICPP on KCE and complete mediating role in the relationship of ICPP and KTE.

摘要

创新城市试点政策（ICPP）的实施有利于推动城市产学研协同创新，但政策对产学研知识流动的影响尚无明确答案。基于知识流动过程分为知识创造阶段和知识转移阶段，本文采用两阶段数据包络分析（DEA）模型来衡量城市产学研知识创造和知识转移的双重效率。并且本文还采用空间差分(SDID)模型研究ICPP对知识流双重效率的影响机制。结果表明，知识创造效率（KCE）和知识转移效率（KTE）具有正的空间溢出效应。而ICPP对产学研KCE和KTE的作用均表现为促进作用。此外，ICPP对城市创新氛围（UIA）有显着的正向影响，UIA在ICPP对KCE的影响机制中起部分中介作用，在ICPP与KTE的关系中起完全中介作用。
