Multi-Type Policies and New Energy Vehicle Innovation Output in China: A Central–Local Perspective

Year: 2026

Type: article

Abstract: To promote the sustainable development of New Energy Vehicles（NEVs）, multilevel governments are formulating an increasing number of policy mixes. A policy mix combines different policy tools from various governance levels, where interactions may occur. Using data from China’s NEV industry, this study creatively divides policies into strategic, supply-side, demand-side and environment-side policies, then further divides the policies into central policies and local policies. Then we investigates how multi-type policies at both the central and local levels affect innovation output and further explores their synergistic effects. The findings show that at the single-level government level, the demand-side subsidy phase-out policies have an inverted U-shaped impact on the innovation output of NEV. And the other multi-type policies exert a positive influence on NEV innovation output. However, when all policies are implemented simultaneously, the involvement of supply-side policy and demand-side policy at the local government level have a policy superposition effect, the effects of local environmental-side policy is crowded out. Synergy is present both within same-type policies and across multi-type policies in multilevel governments. The multilevel governments should pay attention to the coordination and optimization of different types and levels of policies in the NEV industry.
