基于解释结构模型的小城镇再分化内涵解析

An Analysis of the Connotation of Re-differentiation of Small Towns Based on Interpretative Structure Model

小城镇已基本完成以个体最优化为导向、要素局部集聚为内涵的第一次分化。在区域非均衡协调发展的战略共识和网络化的新型城镇功效格局下,分化后部分过度极化、增长低效等问题和个体化内涵的解释失效现象日益凸显,因此合理的再分化是小城镇发展的必然趋势。文章提出将再分化的内涵认知从“个体最优化”向“效能最大化”转变,并建构小城镇发展效能的解释结构模型(ISM)。结果显示,在效能最大化导向下,小城镇再分化的直接影响因素是制度政策作用的力度和周期,其根本性的决定维度是小城镇区域生态价值。同时,与第一次分化中个体经济水平最优决定论不同,再分化过程中小城镇公共服务效率和其区域公共服务能级将是评判其发展效能的决定性要素。

Small towns have experienced a differentiation based on individual optimization and partial elemental agglomeration. In the process of unbalanced regional development and networked urban economic ef ficacy pattern, problems such as excessive polarization, low ef ficiency, and failed explanation of small towns have emerged and a rational re-differentiation of small towns is inevitable in the coming future. The paper proposes conceptual cognition from “individual optimization” to “ef ficacy maximization” for re-differentiation of small towns, and establishes an Interpretative Structure Model (ISM). The paper finds that the intensity and duration of public policy directly affect the re-differentiation of small towns, and the essential factor is the regional ecological value of small towns. Individual optimization is the determinant in the first round of small towns differentiation;whereas in the re- differentiation, public service of small towns and their regional service level are the most valued elements.
