Abstract: As China’s economy soars, environmental challenges grow more pressing. Therefore, the impact of environmental regulations on the green development of forestry has been widely concerned by the society. From the perspective of heterogeneous environmental regulations, this paper explored the effect of heterogeneous environmental regulations on China’s forestry green development. Based on the SBM super-efficiency model method, which includes undesirable outputs, a GML (Global Malmquist-Luenberger) index was constructed to measure forestry green total factor productivity, and the effects of heterogeneous environmental regulations on the green total factor productivity of forestry were empirically investigated by the System GMM estimation method and the threshold effect model. The results show that the impact of different types of environmental regulations on forest green total factor productivity is significantly different, and the impact of ‘command-and-control’ environmental regulations and market-incentive environmental regulations on forest green total factor productivity shows positive “U” shape and inverted “U” shape, respectively. These conclusions remain robust after a series of robustness checks. There are significant differences in the impact of environmental regulations on forestry green total factor productivity in regions with different economic development levels. The ‘command-and-control’ environmental regulations are more suitable for regions with higher levels of economic development, while market-incentive environmental regulations are more suitable for regions with lower levels of economic development. Therefore, it is proposed that in order to promote sustainable development of forestry in China, environmental regulations should be formulated and implemented according to the economic development level and resource endowment conditions of different regions.
