榆林地区城镇化水平综合测度

城镇化水平的科学测度对地区工业化与城镇化，以及地区经济社会的全面协调发展具有重要意义。以16项指标构建陕西省榆林地区城镇化水平综合测度指标体系，采用熵值法对1990—2009年榆林地区城镇化的综合发展水平及城镇化人口子系统、经济子系统、社会子系统和空间子系统的发展水平进行测度。结果表明，榆林地区城镇化水平不断提高，各子系统的贡献差异显著并表现出不同的演变特点。经济子系统的评价得分和增幅最高，其次是空间子系统，而社会子系统和人口子系统发展相对较慢。提高社会子系统的发展水平是榆林地区城镇化发展的关键，人口子系统发展缓慢未来将影响该地区经济子系统的发展。

SYNTHETIC MEASUREMENT OF YULIN`S URBANIZATION LEVEL

Scientific measurement of urbanization level is of significance to industrialization, urbanization and harmonious development of economy and society. This paper uses 16 indicators to establish a synthetic measurement index system to evaluate Yulins urbanization level. It applies entropy to measure the synthetic development level of Yulins urbanization, and the development level of its sub systems of population, economy, society and space from 1990-2009. The results show a rising urbanization level, with variance in contribution of its subsystems. Economy subsystem has the highest score and increment, followed by space subsystem. The development of society and population subsystems is slow. The improvement of society subsystem is the key to Yulins urbanization and the slow development of population subsystem will influence the development of economy subsystem in the future.
