Abstract

According to environmental kuznets curve (EKC), there is a non-linear relationship between economic development and environment pollution. This paper aims to study on the threshold effect of technological ability on environmental pollution and uses nonlinear panel threshold regression to test the effect. An empirical study is made with 19 years panel data from 2000-2018 which are collected from 30 provinces. The study finds out that when taking technological innovation ability as threshold variable, the relationship between economic development and environment pollution is complicated. When technological innovation ability is below the first threshold value, the economic development has positive effect on environmental pollution level. When technological innovation ability ranges from the first threshold value to the second one, the economic development still has positive effect on environmental pollution level, but the effect becomes weak. When technological innovation ability is beyond the second threshold value, the economic development has negative effect on environmental pollution. This paper helps each province to understand the impact of their scientific innovation status on environmental quality and adhere to the concept of innovation and green development.
