【摘要】：采取熵值法对1995—2014年中国高技术产业及其细分行业发展水平进行综合测度,运用相对发展率指数和基尼系数对区域发展差异与空间集聚程度进行分析,并对各细分行业的影响因素进行分别探讨。研究表明,中国高技术产业综合发展水平不断提高,形成了围绕"T"字形高发展水平单元区向外围逐渐递减的空间分布格局;2005—2014年相对发展率指数差异程度较1995—2005年降低,且各单元间综合发展水平差异先增后减;各细分行业虽均有发展,但发展进程不同,分别处于不同的发展阶段,并在各时段呈现出不同的空间分布特征,形成了三种类型的空间集聚模式与演化特征;同一行业影响其发展的因素在发生变化,不同细分行业影响因素不同,未来应细化高技术产业各细分行业发展策略。
[Abstract]:The entropy method is adopted to measure the development level of China's high-tech industry and its subdivision from 1995 to 2014. The relative development rate index and Gini coefficient are used to analyze the regional development difference and the degree of spatial agglomeration.And the influence factor of each subdivision industry carries on the discussion separately.The research shows that the comprehensive development level of China's high-tech industry is constantly improving, which forms a spatial distribution pattern which gradually decreases to the periphery around the "T" zigzag high development level unit area. In 2005-2014, the difference degree of relative development rate index between 2005 and 2014 is lower than that in 1995-2005.The difference of comprehensive development level among different units increases first and then decreases. Although each subdivision industry has developed, the development process is different, and it is in different stages of development, and presents different spatial distribution characteristics in each period.Three types of spatial agglomeration patterns and evolution characteristics have been formed. The factors affecting the development of the same industry are changing. Different subdivision industries have different influence factors. In the future, the development strategies of each subdivision industry of high-tech industry should be refined.
