江苏省典型县域村镇建设格局演化模式

城乡中国转型过程中村镇呈现异质化发展态势。然而当前研究较多关注了村镇物质空间演变特征，忽视了其背后社会经济形态变迁对村镇建设格局的形塑作用。本文以提炼不同发展路径下的县域村镇建设格局演化模式特征为目标，首先从“社会过程—空间形式”视角，剖析村镇建设格局演化路径分化逻辑，并梳理其分化历程；其次采用多案例研究方法，对比分析2009—2018年江苏省3个典型县域的村镇建设格局演化差异；最后将其归纳为具有一定普适意义的演化模式。结果表明：村镇建设格局演化是典型的空间生产过程，在城乡中国转型过程中，生产方式的转变引致村镇建设格局演化路径呈现多元分化；由于要素集聚与疏散的空间需求不同，不同发展路径下的县域村镇建设格局演化时空特征、影响因素作用机制具有显著差异。基于案例比较分析，本文总结出具有差异化演化态势及动力机制的3类演化模式，分别为城乡两极分化的农业生产型、城镇多中心扩张的工业生产型、村庄走向分野的生态消费型，并提出了相应的针对性措施，因地制宜推进城乡融合发展。

The evolution modes of town-villages construction pattern of typical counties:A comparative case study of three counties in Jiangsu province

Town-village shows a heterogeneous development trend in the urban-rural transition in China. However, previous studies focused more on the dynamics of the physical space of town-villages and the impact of natural factors while ignoring the shaping effects of the underlying socioeconomic changes. Scientific understanding of town-villages development rules at the county scale and the refinement of typical evolutionary modes can help construct an efficient and coordinated town-villages construction pattern (TVCP) that adapts to socioeconomic patterns according to local conditions. It also helps to promote industrial reshaping, organisational reconstruction, and spatial reconfiguration of town-villages. More importantly, it can build a new platform for urban-rural integrated development and thus achieve common prosperity for both rural and urban areas. This research aims to refine the evolutionary modes of TVCP in counties with different development paths. First, we analysed the logic and history of the differentiation of the TVCP evolutionary path from the perspective of "social process-space form". Then, a multicase method was used to compare and analyse the differences in the evolution of TVCP in three typical counties of Jiangsu province from 2009 to 2018. Finally, we generalised the experience into universal evolution modes. The results show that the TVCP evolution is a typical process of the production of space, and the transformation of the production mode leads to various evolutionary paths of the TVCP. Moreover, there are obvious differences in the spatio-temporal characteristics of the TVCP evolution and the mechanisms of influencing factors under different development paths due to the difference in spatial demands of element agglomeration and evacuation. Based on the comparative case analysis, we summarise three types of evolutionary modes with different changing trends and dynamic mechanisms. The agricultural production mode shows a trend of polarised expansion of Chengguan town and shrewd contraction of the villages, which is mainly driven by urbanisation combined with state power and social demands. The industrial production mode, driven by rapid capital circulation dominated by market power, shows a trend of polycentric expansion of towns and consolidation of villages. The ecological consumption mode is characterised by the divergence between the revival and decline of villages; the driving mechanism is commodification and authoritativeness in rural space. According to the three modes, we suggest that efforts should be made to equalise basic public services, realise the citizenization of the migrant agricultural population, and promote commercial cooperation between urban and rural areas in the future.
