Evaluation to Chinese marine economy in the coastal areas

TL;DR

This paper evaluates the environmental performance of China's coastal marine economy using data envelopment analysis, comparing traditional and environmentally-adjusted models to guide sustainable development.

Contribution

It introduces an environmental performance index model tailored for China's marine economy, integrating undesirable outputs into efficiency analysis.

Findings

Environmental performance index correlates with economic efficiency and industrial structure.

The environmentally-adjusted model provides a more comprehensive assessment of marine economic sustainability.

Results support policy guidance for sustainable coastal economic development.

Abstract

For promoting the development of the marine economy more sustainably, based on the data envelopment analysis method and combined with the impact of the marine environment, the environmental performance of the marine economy was evaluated for Chinese coastal provinces. Firstly, the classical CCR model was used. Then, a model that considered undesirable outputs was developed to suit the Chinese marine economy. Using the two models, the economic efficiencies without environmental consideration and the environmental performance index were calculated and compared. According to the results, the empirical relationship between EPI and EE, per capita GDP, and the industrial structure was analyzed. It is useful for guiding the coastal local economy of China to a healthy way.
