工业化、城镇化、信息化与农业现代化(简称“四化”)是促进城乡统筹和区域发展的现实需要与战略导向。本文着力构建综合评价指标体系以揭示我国地级区域四化协调发展的空间格局,借助空间计量经济模型探讨四化协调发展的影响因素,结合相关分析探讨四化协调指数与区域发展主要指标的关联关系,建立识别方法开展基于四化发展状态的问题区域识别研究。结果表明:四化各自发展水平、综合指数、耦合度、协调度均存在明显的空间差异;四化协调发展水平越高,区域经济发展水平和农村发展水平越高,而城乡居民的收入差距和消费差距越低;社会经济、交通区位及自然地理类要素对四化协调状况有不同程度的影响,尤以农业和农村的社会投资、财政投入及金融支持,以及大中型企业发展、道路基础设施建设、居民消费等因素对四化协调发展的影响更为稳健而积极;识别出四化发展存在若干问题的7类计145个地市,主要分布在中部传统农区、西南山地丘陵区和青藏高原区。在城乡转型发展新时期,推进四化协调发展既需要共性制度创新,还需要针对问题区域及其区域问题研制区域政策,有必要继续加大对农业农村的社会投资、财政投入与金融扶持力度,积极扩大内需,优化外向型经济发展战略,提升城镇投资和教育投资的效率。
The coordination development of industrialization, informatization, urbanization and agricultural modemization (so called "Sihua Tongbu" in Chinese, and hereinafter referred to as "new four modernizations"; China first put forward the term of "four modemizations" in the early 1960s, targeting the fields of industry, agriculture, national defense and science and technology) is practical need and strategic direction of integrating urban-rural development and regional development in recent China. This study mainly aims to explore the spatial pattern and influencing factors of coordination development of new four modemizations of China's prefecture-level regions. Firstly, we established a comprehensive evaluation index system to reveal the spatial pattern of coordination development of new four modernizations. And then, Pearson correlation analysis was used to explore the relationship between the coordinating degrees of new four modemizations and main indicators reflecting regional development state. Thirdly, a spatial econometric model was employed to explore the factors affecting the coordination development of the new four modernizations. Moreover, a set of rules based on the coordination development level of the new four modemizations has been established to identify the problematic region. The main contents and results were summed up as follows: (1) the respective development level of the new four modernizations and the coupling degree and coordinating degree of the new four modernizations shows obvious spatial difference. (2) The coordinating degree of new four modernizations is at relatively low level, and has significant positive correlation with per capita net income of farmers and per capita gross domestic product, and in contrast, it has significant negative correlation with both the income gap and consumption gap between urban and rural residents. (3) Socio-economic conditions, traffic location and physical geography conditions show obvious impacts on the coordinating stat
