构建城乡协调发展的理论框架与指标体系,基于GIS技术和ESDA方法揭示中国地级市城乡发展协调空间特征,借助空间计量经济学模型探讨城乡协调发展影响因素。研究结果表明：1城乡发展协调体系由要素、结构、功能、政策等层级构成,具有层级内协调与层级间互馈特征。2城乡投资、产业、收入、消费等分项指标均存在明显的空间差异,投资协调指数、产业协调指数、收入协调指数、消费协调指数区域间差距依次减小。3城乡协调发展综合指数空间集聚特征明显,东中西分异,高值区集聚在东部沿海地区和中西部少数中心城市地区。4经济增长、城镇化、对农投资、消费能力的提高有助于城乡协调发展,教育投资、教育水平、基础设施建设对城乡协调发展的作用仍需进一步加强。

英文摘要：

Integrating urban and rural development is the strategy and mostly significant task of people-oriented urbanization. It is of importance to strengthen research on urban-rural coordinated development, to provide scientific supports for urban-rural planning and policy making. We first proposed the theoretical framework of urban-rural coordinated development and established coordinated index system. Then, by GIS and ESDA methods, spatial patterns and characteristics of urban-rural coordinated development were explored, and its influencing factors were analyzed based on spatial econometric model. The results are shown as follows： 1）The urban-rural coordinated development system consists of four subsystems, which are factors, structures, functions and policies. The coordinated urban-rural development depends on the mutual coordination and cooperation of elements within the subsystem and positive mutual feedback evolvement among the subsystems. 2）Sub-indices such as investment, industry, income and consumption between urban and rural areas take on significant spatial differences, respectively. The degree of variation of investment coordination index, industry coordination index, income coordination index and consume index reduces in turn. 3）Urban-rural integrated coordination index shows obviously spatial differences among the east, middle, northeast and west of China, and takes on spatial agglomeration. High-level areas of coordination index gather in the eastern coastal region and a few cities in the central and western China, while low-level areas are mostly located in the central and western China, especially showed in the provincial map. 4） Economic growth, urbanization, rural investment and domestic consumption had significantly positive effects on urban-rural coordination development, while urban investment had negative effects. Meanwhile, education investment, education level and infrastructure did not have significant effects due to the misallocation of resources between urban and rural areas. These
