基于区位熵的西北新兴工业城市职能演进与发展趋势分析--以兰州、西安为例

Analysis on the Evolution and Development Trend of Functions of EmergingIndustrial Cities in Northwest China Based on Location Entropy:Taking Lanzhou and Xi’an as Examples

兰州和西安同属新中国成立初期西北典型苏联援华新兴工业城市,经过70年规划建设发展之后,如今两座城市的经济地位以及城市职能均出现了巨大时空差异。从区位熵分析法入手,分析城市第一、二、三产业的区位熵值和职能,研究兰州、西安从2000年到2019年城市职能演进特征,剖析兰州、西安产业区位熵对比及动态变化,发现兰州第一产业优势较弱,第二产业优势减弱,第三产业具有一定优势;西安与兰州在产业发展上大体相近,第一产业职能总体强度高于兰州,第二产业优势减弱,第三产业优势明显。今后,兰州应持续发展工业职能,强化金融服务职能,做好工业职能转型,提升城市能级;西安生产性与生活性职能应并重发展,强化社会改革管理职能,培育新型城市特色职能,促进产业升级,全面提升核心竞争力。

The Cities of Lanzhou and Xi’an are both typical emerging industrial cities in the northwest of China with Soviet Union’s aid to China,in the early days of the founding of the People’s Republic of China.After 70 years of planning,construction and development,the economic status and urban functions of the two cities now have great temporal and spatial differences.Based on the location entropy analysis method,this paper analyzes values and functions of location entropy of the primary,secondary and tertiary industries in cities,studies the evolution characteristics of urban functions of Lanzhou and Xi’an from 2000 to 2019,analyzes the comparison and dynamic changes of industrial location entropy in Lanzhou and Xi’an,and the results show that Lanzhou’s primary industry has slight advantages,the secondary industry has weakened advantages,and the tertiary industry has certain advantages;Xi’an and Lanzhou are generally similar in industrial development,and the overall strength of the functions of its primary industry is higher than Lanzhou,the secondary industry has weakened advantages,and the tertiary industry has an obvious advantage.In the future,Lanzhou should continue to develop its industrial functions,strengthen financial service functions,implement the transformation of industrial functions,and improve the urban energy level;Xi’an should pay equal attention to the development of productive and living functions,strengthen the functions of social reform management,cultivate functions with new urban characteristics,and promote the upgrade of industrial development and comprehensively enhance core competitiveness.
