How will different types of industry policies and their mixes affect the innovation performance of wind power enterprises? Based on dual perspectives of regional innovation environment and enterprise ownership

摘要

Evaluating the effectiveness and functional boundary of different types of industry policies and their mixes on the innovation performance of wind power enterprises (WPEs) is an important but unresolved key issue. This study, based on dual perspectives of regional innovation environment and enterprise ownership, empirically examines the impacts of different types of industry policies and their mixes on enterprise innovation. The results show that different types of policies have significantly different effects on innovation performance of WPEs; policy mixes have a significant synergy but may not be fully effective, and environmental-side policy and demand-side policy mixes still show significant inhibition. Taking into account boundary conditions, this study finds that policy mixes are implemented better in regions with weak innovation environments, especially in terms of the innovation performance of private-owned WPEs in the region. However, there is no significant impact for WPEs located in regions with strong innovation environments and state-owned enterprises in regions with weak innovation environments. This study expands an understanding of external boundaries for the effective implementation of different industry policies and their mixes, and has important implications for China in improving the applicability and matching ability of policies in the wind power industry.
