东北三省旅游经济质量的区域差异、动态演进及影响因素

采用SBM模型、Dagum基尼系数及分解方法、核密度估计法对东北三省36个城市旅游经济增长质量的区域差异及动态演进进行研究。结果表明：① 东北三省旅游经济增长质量总体水平不高，存在明显的区域差异；② 从差异来源及其贡献度来看，2007—2010年超变密度是地区差异的主要来源，2011—2018年地区间差异是差异的主要来源；③ 东北三省旅游经济质量总体核密度曲线逐渐向右移动，旅游经济质量水平不断提升，区域旅游经济差异逐渐减小；④ 旅游资源禀赋、生态环境和社会经济发展水平对旅游经济质量差异产生影响。

Regional Differences,Dynamic Evolution and Influencing Factors of the Quality of Tourism Economy in Northeast China

SBM model, Dagum Gini coefficient and decomposition method, and kernel density estimation method are used to study the regional differences and dynamic evolution of the quality of tourism economic growth in 36 cities of Northeast China. The results show that: 1) The overall level of the quality of tourism economic growth in the three northeastern provinces is not high, and there are obvious regional differences; 2) From the perspective of the sources of differences and their contributions, The over variable density in 2007-2010 is the main source of regional differences, and 2011-2018 is the main source of regional differences; 3) The overall core density curve of tourism economic quality of the Three Northeastern Provinces is gradually moving to the right, the level of tourism economic quality is constantly improving, and the regional tourism economic differences are gradually decreasing; 4) Tourism resource endowment, ecological environment and social and economic development level have an impact on tourism economic quality .
