Most environmental policy studies focus on the technical pathway effect but ignore the non-technical pathway. This paper analyzes the synergistic governance effects of three types of environmental policies on the technical and non-technical pathways. The super-efficient slacks-based measure-data envelopment analysis (SBM-DEA) assesses the green total factor productivity, while the Malmquist index decomposes into pure technical efficiency. The findings indicate that: (1) command-and-control policy has the 'too-little-of-a-good-thing' effect, but the policy intensity in most Chinese provinces is strong enough to reduce air pollution, while market-based incentive policy may be 'too-much-of-a-good-thing', but Chinese provinces have not reached the inflection point; (2) there are considerable differences in the environmental effects of different policies through technical and non-technical pathways; (3) different policies have various focuses. Command-and-control policy focuses on the non-technical pathway, whereas market-based incentive policy can induce technological progress. • Technical change is used to measure green technology progress. • CACP has a 'too-little-of-a-good-thing' effect and MBIP may be 'too-much-of-a-good-thing'. • The effect curves of different polices have different shapes and inflection points. • Three policies need to achieve synergies on two pathways.
