Research on the uncertainty of low-carbon environmental governance system and its impact on the dual goals of carbon emission reduction

Based on the theoretical analysis of different dimensions of China's low-carbon governance environment, the uncertainty index of the low-carbon governance environment is constructed, and the fuzzy comprehensive evaluation of China's low-carbon governance environment is carried out based on the improved analytic hierarchy process and an entropy weight method. The dynamic panel model and PSTR transfer model are established to divide the degree of environmental uncertainty in low-carbon governance and to explore the regional heterogeneity impact of environmental uncertainty on the dual goals of carbon emission reduction. The empirical results show that as the uncertainty of the low-carbon governance environment changes from a low-zone system to a high-zone system, its negative impact on the realization of the dual goal of carbon emission reduction is gradually strengthened. The uncertainty of low-carbon governance environment will hinder the realization of China's carbon emission reduction targets. Stable low-carbon policy environment and economic environment are conducive to promoting carbon emission reduction targets from environmental governance, while the stability of technological innovation environment and carbon trading mechanism is an important factor in promoting carbon emission reduction targets.
