However, ecological protection and supporting infrastructure are prerequisites accompanied by the rapid development of tourism. To measure the tourism potential, we intend to analyze the sustainable development of tourism and get the related countermeasure for policy-making assistance. The sustainable development of tourism potential in Shanghai is measured by the MFA evaluation model based on the construction of 3 core systems in sustainable development. According to the evaluation results, we analyzed the reason for the score’s decline of the sustainable development ability of provincial tourism of Shanghai is from a shortage of industrial positioning, insufficiency, insufficient fusion, and obliterated cooperation in this industry. Countermeasures for provincial tourism development from perspectives of economy, culture, society and political technology could be given as economic mutual promotion and reflection, adjustment of tourism industrial development pattern, improvements in the policy guidance and regulation of tourism investment. Keywords: MFA, tourism industry, sustainable development.","PeriodicalId":209131,"journal":{"name":"International Journal of Ecology and Ecosolution","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125689094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
