市场准入管制放松与企业技术多元化

Abstract

Although existing literature has confirmed the innovation effect of relaxing market access regulations, it has not delved deeply into the specific technological direction. The results of this paper show that: (1) The pilot of the negative list system for market access significantly improved the technological diversification level of enterprises in the pilot areas, an effect mainly reflected in groups with higher technological uncertainty, broader inventor knowledge coverage, higher enterprise digitalization, and lower financing constraints. (2) After the pilot, enterprises tend to develop entirely new technological directions, abandon secondary technological directions, and improve technological efficiency. Meanwhile, the standard competition, technological competition, and product market competition they face have intensified significantly, indicating that the relaxation of market access regulation enhances enterprise technological diversification through technological resource allocation mechanisms and competition mechanisms. (3) After the relaxation, the improvement in enterprise technological diversification produced positive economic consequences, significantly enhancing the level of disruptive innovation and total factor productivity. This paper enriches the existing research on the innovation effects of relaxing market access regulations from two aspects: deepening from overall innovation to innovation in various technological directions, and expanding from product market competition mechanisms to standard and technological competition mechanisms.
