多元创新政策对新能源企业创新影响的研究
The Impact of Diverse Innovation Policies on Innovation of New Energy Enterprises
摘要
Abstract
With the deepening of the green development concept,the new energy industry has become increas-ingly prominent.However,the innovation policies that rely solely on supply-side R&D subsidies are gradually re-vealing their limitations.How to better leverage the pulling effect of demand-side policies,such as innovation pro-curement,has become an urgent issue of concern for policymakers and stakeholders.This paper explores the differ-ent effects of supply-side R&D subsidies and demand-side innovation procurement policies,and reveals the mecha-nisms of policy influence from a resource-based perspective,providing theoretical support for building a more effec-tive innovation policy system in China. Using a sample of new energy enterprises from the Shanghai Science and Technology Survey Data from 2008 to 2017,this paper examines the impact of R&D subsidy policies and innovation procurement policies on firm innova-tion.The new energy sector,characterized by high technological dependence and innovation intensity,is a key tar-get of various innovation policy instruments.The conclusions remain robust after conducting a series of robustness checks,such as instrumental variable estimation,inclusion of interactive fixed effects,and propensity score matc-hing(PSM). The empirical findings are as follows.First,both R&D subsidies and innovation procurement significantly pro-mote innovation activities in new energy enterprises.Resource dependence theory suggests that R&D subsidies tend to be homogeneous with firms' internal innovation resources,leading to diminishing policy effects as internal re-sources become more abundant.In contrast,innovation procurement is heterogeneous and complementary to inter-nal innovation resources,with policy effects increasing alongside greater internal resource availability.Second,fur-ther analysis indicates that neither type of policy significantly reduces innovation quality.Compared to R&D subsi-dies,innovation procurement is more effective in promoting high-quality innovation outputs,as measured by inven-tion patents,and repeated implementation of procurement policies contributes to further improvement in innovation quality.Third,heterogeneity analysis reveals that the incentive effect of R&D subsidies is broadly applicable across firms.Innovation procurement,however,significantly promotes open innovation and the number of invention patent grants among small and medium-sized enterprises(SMEs).For non-open innovation firms and large enterprises,the positive effect of innovation procurement is observed mainly in non-invention patents. This paper has the following contributions.First,by comparing the effects of supply-side R&D subsidies and demand-side innovation procurement policies,it reveals the differentiated impacts and mechanisms of heterogeneous innovation policies.Second,it highlights how the abundance of internal innovation resources and the degree of a-lignment between internal and external resources influence the effectiveness of innovation policy instruments,offer-ing new insights from the perspective of resource dependence theory.关键词
