摘　　要：基于熊皮特内生增长理论和空间经济学视角,利用空间动态杜宾模型探讨了产业集聚对城市创新的作用机制。研究发现,专业化与多样化集聚对城市创新的长期效应优于短期效应,但二者作用效果不同。其中专业化与多样化集聚通过规模效应促进本地城市创新,而专业化集聚并未通过技术外溢效应为本地和邻近企业带来创新,多样化集聚的技术外溢效应对本地创新具有抑制作用。进一步研究发现,政府主导下的专业化集聚易形成创新惰性,不利于本地及周边区域产业创新;各地政府对中央政府产业集聚政策的模仿导致产业同质化集聚,加剧了产业间对有限资源的竞争,不仅无法发挥多样化的Jacobs外部性,反而阻碍城市创新。城市产业集聚对城市创新的影响具有区域异质性,长三角和珠三角地区的专业化与多样化集聚具有空间极化效应,这些区域特征对各地区因地制宜制定城市创新政策具有重要借鉴意义。Based on Schumpeter's endogenous growth theory and spatial economics, this paper uses the spatial dynamic Dubin model to explore the mechanism of industrial agglomeration on urban innovation. The results show that the long-term effect of specialization and diversification agglomeration on urban innovation is better than the short-term effect, but their effects are different. Among them, specialization and diversification agglomeration promote local urban innovation through scale effect, but specialization agglomeration does not bring innovation to local and neighboring enterprises through technology spillover effect, and the technology spillover effect of diversification agglomeration has an inhibitory effect on local innovation. Further research shows that the specialization agglomeration led by the government is easy to form innovation inertia, which is not conducive to industrial innovation in the local and surrounding regions. Local governments' imitation of the central government's industrial agglomeration policy leads to homogenized industrial agglomeration, intensifies the competition between industries for limited resources, and not only fails to give play to diversified Jacobs externalities, but hinders urban innovation. The influence of urban industrial agglomeration on urban innovation has regional heterogeneity, and the specialization and diversification agglomeration in the Yangtze River Delta and Pearl River Delta have spatial polarization effect. These regional characteristics have important reference significance for various regions to formulate urban innovation policies according to local conditions.
