Assessing the Coordinate Development Between Economy and Ecological Environment in China's 30 Provinces from 2013 to 2019

For all developing countries, how to coordinate the interaction of industrial production and environmental protection in the process of economic development is a common challenge. In the past few decades, the Chinese government has realized that rapid economic development has brought about environmental pollution issues. Therefore, during the 12th and 13th Five-Year Plan period (2011-2015 and 2016-2020), a series of objectives and tasks on improving the quality of the atmosphere, water, soil, and ecological environment have been formulated by the Chinese government, which made solid progress. Based on the entropy weight TOPSIS (technique for order performance by similarity to ideal solution) method and the coupling and coordination degree model (CCD model), this paper selected 14 indicators of the ecological environment and the economic system to evaluate the coordinate development of 30 provinces in China (except Tibet) from 2013 to 2019. The results show that in the past few years, the coordinated development in most regions has continued to improve, but still maintained in the transitional state of coordinated development, because the current effectiveness of China's battle against pollution is not stable, and the industrial structure dominated by heavy industry and chemical industry, and the energy structure dominated by coal have not fundamentally changed. Based on this conclusion, we provided some suggestions for the national and provincial institutes to reduce pollutants and carbon emissions, and continuously improve the quality of the ecological environment by adhering to the strategy of green and low-carbon development.
