河南省生产性服务业的空间优化布局对于区域产业调整、制造业发展,促进河南经济发展具有重要意义.运用全局主成分分析、克鲁格曼专业化指数、空间基尼系数、区位熵等方法从区域和行业两个视角分析河南省生产性服务业集聚水平的时空特征.结果表明:①从区域视角来看,运用全局主成分分析,在时间维度上,只有郑州得分一直呈上升趋势,且变化较大,其他省辖市则变化不大;在空间上差异明显,郑州集聚水平处于绝对优势.运用克鲁格曼专业化指数分析,时间维度上生产性服务业专业化程度不高,产业结构有异化的趋势,但从空间角度来看,除濮阳外产业结构整体变化不大.②从行业视角来看,在时间维度上,除科学研究、技术服务和地质勘查业以及批发和零售业外,其他分行业和整个生产性服务业集聚水平都大致呈倒“V”形分布,整体上呈上升趋势,且知识和资本密集型行业集聚水平较高;从空间角度来看,市域范围内,整个生产性服务业及各分行业集聚格局整体相对较稳,局部变动明显.
The spatial optimal layout of producer services in Henan Province is of great significance to the adjustment of regional industries, the development of manufacturing industry and the economic development of Henan Province.Using the methods of global principal component analysis, Krugman specialization index, space Gini coefficient, location entropy and so on Regional and industry perspectives were used to analyze the spatio-temporal characteristics of agglomeration level of producer services in Henan Province.The results showed that: ① From a regional perspective, using the global principal component analysis, in the time dimension, only Zhengzhou scores have been on the rise, While the other provincial cities did not change much.The differences in space were obvious and Zhengzhou agglomeration level was in absolute advantage.Using the Krugman specialization index analysis, the degree of specialization of producer services in time dimension was not high, and the industrial structure There is a tendency of alienation, but from the perspective of space, the overall industrial structure except Puyang has little change overall.② From an industrial perspective, in the time dimension, in addition to scientific research, technical services and geological prospecting as well as wholesale and retail , The concentration levels of other sub-industries and the entire producer service industry were roughly “V” shaped, with an overall upward trend, and knowledge and capital Type set higher industry concentration level; from the space point of view, within the municipal area, the entire productive service industry and its sub-cluster pattern as a whole is relatively stable, significant local variations.
