基于Theil指数的广东省入境旅游经济时空差异研究

运用Theil指数定量评价了1990-2009年广东省入境旅游经济时空尺度上的市际、地带间和地带内差异变化状况,其结论如下:(1)在时间尺度上,广东入境旅游经济市际差异Tp、地带内差异Twr演变呈逐渐收敛趋同的阶梯状下降趋势；珠三角地带间及地带内差异也呈阶梯状下降,东翼、西翼、山区地带间及地带内演变趋势不明显.(2)在空间尺度上,广东省入境旅游经济发展存在非均衡性,市际差异Tp主要来源于地带内差异Twr的贡献,尤其是珠三角地带内差异的贡献；珠三角与东翼、西翼、山区地带间差异较大,而东翼、西翼、山区地带间差异很小,地带间差异Tbr指数珠三角＞东翼＞山区＞西翼.引入区域分离Separation(缩写为SEP)指数来定量比较广东省四大地带入境旅游经济分离收敛的空间变化规律,并对广东省入境旅游经济发展提出相关建议.

Analysis on Spatio-temporal Diversity of Inbound Tourism in Guangdong Province Based on Theil Coefficient

With the help of Theil coefficient,this paper makes a quantitative analysis of measuring spatio-temporal changes of inter-urban,inter-regional and infra-regional diversity of inbound tourism of Guangdong during 1990—2009.The results can be summarized as follows: First,in the time scale,inter-urban diversity,inter-regional diversity and infra-regional diversity of Pearl River Delta are on the decrease,which show the trend of gradual convergence,the trend of inter-regional and infra-regional diversity of western,eastern and mountainous in Guangdong Province are not obvious;Secondly,in the spatial scale,inbound tourism economic development of Guangdong Province has non-equilibrium,inter-regional diversity is the main contributor to inter-urban tourism diversity,inter-regional diversity in Pearl River Delta is the major contributor;the inter-regional diversity between Pearl River Delta and western,eastern and mountainous in Guangdong Province is larger,the inter-regional diversity between western,eastern and mountainous in Guangdong Province is smaller,the size of Theil coefficient is Pearl River Delta>eastern>mountainous>western.Then this paper introduces regional separation coefficient to quantitatively compare the law of inbound tourism change among four areas in Guangdong Province.Finally,this paper proposes some advices to develop inbound tourism economy of Guangdong Province.
