关中-天水经济区旅游经济空间差异演化分析

Analysis on Spatial Differential Evolution of Tourism Economy in Guanzhong-Tianshui Economic Zone

以关中—天水经济区为样本,运用锡尔系数、赫芬达尔指数、地理集中指数、区位熵等指标和偏离—份额分析法,实证研究了2009—2013年经济区旅游经济的总体差异及地区差异。结果表明:自经济区成立以来,总体上旅游经济相对差异在逐年缩小,旅游市场集中度呈现出地域扩展态势,旅游地理集中度虽有下降但仍处于较高水平;各地旅游总收入空间偏离主要取决于其内生的增长动力,部分城市旅游业单极化发展,旅游经济地区间不平衡趋势明显。

This paper took Guanzhong-Tianshui economic zone as an example to analyze the overall difference and the regional difference of tourism economy from 2009 to 2013 by using Theil index,Hirshmann-Herfindahl index,geography concentration index,location entropy and the shift share analysis method.It showed that since the economic zone established,generally the relative differences of tourism economy was reducing year by year,the tourism market concentration had a trend of geographical expansion,the tourism geographic concentration had decreased but still at a high level.The spatial deviation of total tourism revenue mainly depended on the power of endogenous growth,some cities＇ tourism developed in single polarization,and the regional difference of tourism economy was obvious.
