关中-天水经济区经济发展时空差异研究

为了分析关中-天水经济区2007~2015年经济发展时空差异状况，采用变异系数、相对发展率、区位熵等方法进行综合分析。研究表明:2007~2015年，经济区经济发展相对差异逐年减小，整体的发展水平逐年提高；而绝对差异不断扩大，西安、咸阳的经济发展水平相对较高，商洛和天水水平最低。研究期内，西安、咸阳、渭南一直都是经济发达地区，其经济发展相对经济区的平均经济发展速度要迅速，而商洛、天水的发展速度最靠后；西安相对经济区的平均发展速度最快，商洛的经济增长最为明显但发展水平较低。经济区产业结构已经实现了以工业和服务业为主的格局，但发展水平较低；各地市间产业结构差异较大；西安、杨凌的产业结构较为合理，而天水的产业结构需进一步完善。研究结果表明，为促进关中-天水经济区的和谐、高效发展，经济区内各地市在增强自身经济实力的基础上，还应加大相互间的科技、人才和信息交流，充分发展与利用物流、经济信息平台等，推动经济区产业转移与合理布局，逐步缩小地区间发展差异，促进经济区经济社会的健康高效发展。

Study on the temporal and spatial difference of economic development in Guanzhong Tianshui economic zone

In order to study the spatial and temporal differences of economic development in Guanzhong Tianshui economic zone in the past 2007~2015 years, comprehensive analysis was carried out with the methods of coefficient of variation, relative development rate and location entropy. Research shows that from 2007 to 2015, the region economic development relative difference has decreased year by year, and the overall level of development has increased year by year . But the absolute difference has been constantly expanding. The economic development levels of Xi’an, Xianyang are relatively high, and the lowest is in Shangluo and Tianshui area.In study period, Xi’an, Xianyang and Weinan have always been economically developed areas. The economic development speed is more rapid than the average speed of the economic development of the economic zone, while the development speed of Shangluo and Tianshui is the lowest. Compared with the average development speed of relative economic zone, Xi’an has the fastest economic growth. Shangluo has the most obvious economic growth but the low level of development. The industrial structure of economic zone has achieved the pattern of mainly industrial and the service industries , but the development level is relatively low. The industrial structure varies greatly among cities. The industrial structure of Xi’an and Yangling are more reasonable while the industrial structure of Tianshui needs to be further improved. The results show that in order to promote the harmonious and efficient development of Guanzhong Tianshui economic zone , all localities in the economic zone should increase their economic, technoligical , talents and information exchange with each other and fully develop and utilize logistics and economic information platform and so on, to promote the industry transfer and reasonable layout of economic zone and gradually narrow the regional development differences between regions to promote the economic and social development of the economic zone in a healthy and efficient manner.
