跨区域重大基础设施空间效应评估的理论框架

Theoretical framework of spatial effect assessment of major trans-regional infrastructure

跨区域重大基础设施建设是国家政治、经济、社会和技术进步的共同体现,也是服务资源优化配置、社会经济协调发展和优化国土空间治理体系的重要手段,如何科学地认识并评估其空间效应成为当前学术界亟需解决的理论性问题。在系统梳理中国跨区域重大基础设施概念内涵、类型与职能、发展历程的基础上,从地理学和经济学视角解析跨区域重大基础设施空间效应的理论内涵、基本特征和形成机制,从评估目标、评估内容和评估方法3个方面构建空间效应评估理论框架,以期为跨区域重大基础设施的评价与布局优化提供指导。

The construction of major trans-regional infrastructure is a reflection of national political,economic,social,and technological progress.It is also an important means of optimizing resource allocation,promoting coordinated socio-economic development,and optimizing the governance system of national territorial space.How to scientifically understand and evaluate its spatial effects has become a theoretical problem that the academic community needs to solve.The'Five-in-One'economic,social,ecological,cultural,and political effects of major trans-regional infrastructure overlap and interact with each other.A reasonable evaluation of their comprehensive effects not only meets the needs of national regional development strategies,but also promotes the solution of practical problems.Against this background,based on the needs of decision-making for the construction and operation of major trans-regional infrastructure,this study systematically sorts out the connotation,types,and functions,as well as the development process of major trans-regional infrastructure in China,and analyzes the theoretical connotation,basic characteristics,and formation mechanism of the spatial effects of major trans-regional infrastructure from the perspectives of geography and economics,and studies the construction of its evaluation framework.The results show that although the theoretical connotation of the spatial effects of major trans-regional infrastructure is constantly expanding with the development of relevant theories,it presents obvious characteristics of comprehensiveness,regionality,and dynamics.Its formation mechanism mainly involves location creation,factor flow,and agglomeration effects.At the same time,considering that the comprehensive evaluation of the spatial effects of major trans-regional infrastructure needs to achieve multiple goals,and different goals often focus on different content and adopt different methods,the evaluation framework and method system should include three levels:evaluation goals,evaluation content,and evaluation methods.Therefore,it can provide practical guidance for the layout optimization of major trans-regional major infrastructure.
