Gu, Q.Y.; Wang, R., and Ju, C.H., 2020. Evaluation path selection of opening-up level of Chinese coastal cities based on entropy weight-topsis-grey correlation: From researches on ten coastal cities. In: Bai, X. and Zhou, H. (eds.), Advances in Water Resources, Environmental Protection, and Sustainable Development. Journal of Coastal Research, Special Issue No. 115, pp. 636-640.

The article provides a system to evaluate the opening-up level of coastal cities in China based on literatures and the national conditions of China's opening-up. Targeting relevant data and opening-up level of ten typical coastal cities in China, It solves performance differences and weights of indexes by using the entropy weight method, scores the cities' opening-up level through weighted TOPSIS method and make judgement on the correlation between samples and various indexes through grey correlation method. At last, it make propositions on further opening-up of coastal cities in China.
