Abstract

Qu, G.J., 2020. An evaluation method for water pollution treatment efficiency in coastal cities based on regional management. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 100–103. Coconut Creek (Florida), ISSN 0749-0208.At present, coastal cities are constantly enhancing their water pollution treatment capabilities, so how to evaluate the efficiency of water pollution treatment is very important. This paper takes Shenzhen as an example to analyze the current status of the water pollution in Shenzhen city, China; first, it adopts the model of data envelopment analysis (DEA model) to measure the water pollution treatment efficiency; then the paper applies the Tobit model to conduct regression analysis on the influencing factors of water pollution treatment efficiency in coastal cities. The research results show that there are serious water pollution problems in coastal cities across the country. The central government and local governments attach great importance to water pollution treatment, and have invested a lot in coastal cities for this. With the increasing investment in water pollution treatment in coastal cities, the treatment capability and related systems have been improved further, and the water pollution treatment works have achieved certain results. Economic level, population density, and urbanization rate can positively affect the efficiency of water pollution treatment in coastal cities, and the industrial structure and the degree of opening up can adversely affect the efficiency of water pollution treatment in coastal cities. This paper aims to play a role in promoting the efficiency of water pollution treatment in coastal cities.
