江苏作为“一带一路”战略的交汇点,有必要探究其各地区外向型经济发展能力.马氏距离具备消除指标间的相关性且不受量纲影响,代替TOPSIS中的欧氏距离,运用灰色关联度来判断指标的关联性,建立基于马氏距离、灰色关联度的TOPSIS外向型经济发展能力评价模型.以江苏13个地级城市为研究对象,进行实证研究.研究表明,外向型经济发展能力评价模型有助于综合判断各城市外向经济发展能力,发现短板并加以整改,促进“一带一路”建设.
As the meeting point of “Belt and Road” strategy, it is necessary to explore the ability of each region to develop its export-oriented economy.Majang distance has the relativity between elimination indexes and is not influenced by the dimension. Instead of the Euclidean distance in TOPSIS, To establish the evaluation model of TOPSIS outward-oriented economic development capability based on Mahalanobis distance and gray relational degree by using the gray relational degree to determine the relevance of the indicators.Taking the 13 prefecture-level cities in Jiangsu as an example, the empirical study is carried out.The results show that the outward-oriented The evaluation model of economic development capability is helpful for comprehensively judging the ability of each city to develop its outward economy, finding the short board and rectifying it, and promoting the construction of the “One Belt, One Road”.
