安徽省公路交通与经济发展水平测度及协调性研究

Study on the Measurement and Coordination of Road Traffic and Economic Development in Anhui Province

在中国经济发展"新常态"和"长江经济带"战略的宏观背景下,对公路交通与经济发展水平的测度及时空格局进行分析,能够为区域协调均衡发展提供较好的理论和实践指导。以安徽省16个地级市为实证,选择2005、2010、2015年3个时间节点,构建综合评价指标体系,运用熵值法、变异系数、协调指数等方法,分析公路交通和经济发展水平的时空格局和协调发展程度。结果表明:(1)安徽省经济发展水平变异系数较大,公路交通变异系数较小,二者区域内部差异明显;(2)安徽省公路交通发展水平逐年提升,在空间上呈现由"Z"型向"V"型转变继而转向"Z"型的分布格局;经济发展水平整体提升,局部波动,在空间上表征出典型的以合芜马为核心的"核心—边缘"分布特征;(3)公路交通与经济发展水平协调程度整体由协调向失调转变,在不同的时间序列上形成了不同的城市发展主导类型,以协同型和交通滞后型为主。

Measuring the coordination and analyzing the spatial-temporal pattern between regional road traffic and the level of economic development can provide a better theoretical and practical guidance for a balanced development in the development stage of ＂New Normal＂and the strategy of ＂Yangtze River Economic Belt＂.Based on the study of 16 cities in Anhui Province,this paper chooses three time nodes which are 2005,2010 and 2015 to construct a comprehensive evaluation index system, then uses the entropy method, variation coefficient and coordination index to analyze the spatial-temporal pattern and coordination level between road traffic and economic development. The results show that：（ 1） The variation coefficient of economic development level is large,but that of road traffic is small,while the regional difference of both is obvious in Anhui Province.（ 2） The development level of road traffic in Anhui Province has been increasing year by year,and the distribution pattern has been changed from ＂Z＂type to ＂V＂type and then to ＂Z＂type. The level of economic development has been integrally improved,and represents a typical Core-Periphery distribution in which the region of Hefei-Wuhu-Ma Anshan is the core.（ 3） The coordination degree between road traffic and economic development level is changed from coordinated to imbalance overall,meanwhile different urban development types are formed in different period,in which coordination and traffic lag are the main types.
