Abstract: This paper theoretically analyzes the impact of manufacturing servitization on urban innovation and empirically examines it with the data of manufacturing sectors in 287 prefecture-level cities in China. The results show that manufacturing servitization has a significant promoting effect on innovation. Raising the level of manufacturing servitization is conducive to increasing the inputs of innovation funds and knowledge, thereby promoting urban innovation. Considering the heterogeneity of cities, there are different innovation effects of manufacturing servitization between cities: compared with the central and western cities, the impact in eastern cities is greater; compared with the third-tier and smaller cities, the impact in first-tier and second-tier cities is greater. The innovation promoting effect of manufacturing servitization in provincial capital cities would produce a certain spillover effect. In terms of technological element heterogeneity, distribution servitization, financial servitization and sci-tech servitization are the main sources of the innovation effect, while manufacturing servitization has a stronger facilitating effect on substantial innovation. The results of extension study on urban development strategies reveal that the strategies of increasing labor income, boosting foreign investment and enhancing industrial subsidies could induce greater promoting effect of manufacturing sertization on urban innovation than increasing investment, expanding export and introducing tax incentives. This paper provides some policy inspirations for the relevant departments to formulate various innovative development programs according to different urban conditions.
