Did China's dual-credit policy promote innovation in new energy vehicle enterprises? An empirical study based on the PSM-DID method

Abstract

IntroductionBased on the microdata of 36 A-share new energy vehicle (NEV) enterprises from 2015 to 2021, this study empirically investigates whether the introduction of the double credit policy (DCP) promoted the innovation of NEV enterprises.MethodsThe propensity score matching difference-in-differences (PSM-DID) method was used.ResultsThe following results were found. First, the introduction of the DCP inhibits the innovation of NEV enterprises. However, as the DCP stabilizes, the inhibitory effect gradually decreases and shows a tendency to turn into a facilitating effect. Second, the DCP affects the innovation output of enterprises by influencing their research and development (R&D) investment. R&D investment has a mediating role in the DCP, affecting the innovation of new energy vehicle enterprises. Third, at the firm level, the inhibitory effect of the DCP is more evident in non-state-owned enterprises (non-SOE) and insignificant for state-owned enterprises (SOE), while at the regional level, the inhibitory effect of the DCP is more evident for non-eastern regions and insignificant for eastern regions.DiscussionThis study finds the inhibitory effect of the implementation of the DCP on the innovation of NEV enterprises and have potential guiding significance for the future formulation of NEV market development policies and the promotion of high-quality development of the NEV industry.

How does China’s green credit policy affect the innovation of high-polluting enterprises? From the perspective of innovation quantity and quality

“…First, previous studies only use the "quantity" of innovation as a measure of enterprise innovation to study factors affecting enterprise innovation, neglecting the diversity and complexity of innovation and failing to provide a comprehensive assessment of enterprise innovation [ 76 , 77 ]. This paper undertakes a thorough analysis of the impact of the policy on enterprise innovation, considering both the aspects of "quantity" and "quality".…”
