Using the Entropy and TOPSIS Models to Evaluate Sustainable Development of Islands: A Case in China

China is a major maritime country with numerous islands, which are rich in natural resources. Island resources exhibit excellent development potential; this regard, the market demand for uninhabited island has been strong. The scientific and reasonable utilization of islands can create huge economic value region country, inject vitality into national economy, enhance stability overall sustainable economy. However, previous research on focused limited area economy or ecology, few studies provide comprehensive evaluation development. Such requires enormous investment profound impact. Therefore, system necessary planning. This paper accordingly develops an planning indicator based multi-criteria decision-making (MCDM), entropy analysis method, approach Technique Order Preference by Similarity to Ideal Solution (TOPSIS). A validation was conducted prove effectiveness system. comprehensively considers both ecological factors, makes up one-sidedness focusing effectively ensures In important guidance government’s management enterprises. also new ideas islands.
