The Effectiveness of Environmental Policy Mix: Evidence from the Zhejiang Sewage Treatment Policy

Abstract

The development of more effective environmental policies is a common concern among scholars, government and the public. This paper attempts to investigate whether the environmental policy mix can really work. Taking the “Five Water Co-Treatment” policy of Zhejiang Province as an example, we applied the synthetic control method to examine the impact of multi-objective environmental policies on industrial sewage discharge and urban sewage discharge in Zhejiang. Further, we analyzed the effect of industrial value added and the length of water pipelines on sewage discharge and examined the potential environmental Kuznets curve (EKC) relationships. Our results of synthetic control imply that the “Five Water Co-Treatment” policy has increased the industrial and urban sewage discharge. However, the results of the extended analysis show that this is a process of standardizing sewage discharge and an embodiment of enhanced sewage treatment capacity. Therefore, we believe that the “Five Water Co-Treatment” policy is effective and should continue to advance.

Measurement and Prediction: Coupling Coordination of Finance and Air Environment

“…On the contrary, finance has significant impacts on the air environment. When finance is orderly concentrated and developed, it will help improve the quality of the air [8]; otherwise, it is likely to lead to air environmental problems such as air pollution and haze via various approaches or activities [9][10][11][12][13][14].…”

Políticas públicas y la gestión de la calidad ambiental para la descontaminación de ríos

“…(Antúnez Sánchez & Guanoquiza Tello, 2018) El desarrollo de políticas eficaces de gobernanza medioambiental es una cuestión importante que preocupa tanto a la comunidad científica como a la política. (Wu et al, 2020) Como puede observarse, existe la necesidad de proteger la salud pública, y para ello es importante realizar diferentes estudios que permitan implementar propuestas o acciones que contribuyan al buen manejo de las aguas residuales y por consecuente, a la descontaminación de las fuentes de agua superficiales lo que le da una importancia social y ambiental. Además, se ha podido observar la falta de un estudio recopilatorio de las diferentes políticas públicas que se han considerado para tomar acciones sobre la contaminación de los ríos, y de la gestión de calidad ambiental, es por eso que este estudio tiene valor teórico.…”
