摘　　要：前瞻性地探讨交通一体化驱动下可达性对产业空间演化的作用规律,将为产业选址布局和功能定位及其相关政策体系制订等工作提供参考依据。论文以长三角地区生产性服务业为例,构建可达性空间模型测算县区可达性值,运用空间杜宾模型测度可达性对产业空间格局的作用强度及其变化趋势,揭示交通一体化驱动下可达性对生产性服务业空间演变的作用机理。结果显示:①2010年和2020年全部和分行业生产性服务业高值区和高增长区呈现出等级分布和中心城市邻近分布。②在交通一体化驱动下,长三角地区外围地区城市和核心城市可达性水平大幅度提高,可达性格局呈现东西扁平化的“核心—外围”结构,它对生产性服务业空间格局产生直接作用和间接作用。在直接作用中,综合交通可达性对生产性服务业空间格局的作用加强,高铁可达性对生产性服务业发展格局影响显著;在间接作用中,可达性通过空间集聚、空间竞争和市场潜力等因素对生产性服务业空间格局产生重要影响。③邻近县区空间集聚效应和空间竞争因素对本地生产性服务业空间格局的正负向作用增强。市场潜力是生产性服务业企业选址布局的主导因素,县区只有在具备足够市场潜力的基础上,高水平可达性才能在吸引生产性服务业企业落地上起到关键作用。④可达性不但具有推动生产性服务业企业扩散的“离心力”,也包含促进企业集聚的“向心力”,二者共同影响生产性服务业企业空间选址与区位迁移决策。据此,面对区域交通一体化水平的日趋提升,各地可以根据不同行业对可达性的敏感程度和区位偏好差异,因地制宜地规划布局交通枢纽地区生产性服务业产业集群。Prospectively exploring the role of accessibility on the evolution of industrial space driven by transportation integration will provide a reference for industrial site selection,functional positioning,and the formulation of related policy systems.Taking the producer service industry in the Yangtze River Delta region as an example,this study constructed a spatial accessibility model to measure county accessibility values,and used GIS spatial analysis and spatial Durbin model to measure the intensity of the impact of accessibility on industrial spatial patterns and trends of change,which can reveal the mechanism of accessibility's effect on the spatial evolution of producer services driven by transportation integration.The results indicate that:1)In 2010 and 2020,the high-value areas and high-growth areas of producer services in all and sub-sectors showed hierarchical distribution and distribution near central cities.2)Driven by transportation integration,the accessibility level of cities in peripheral areas and core cities in the Yangtze River Delta region has been greatly improved.The accessibility pattern presents a flat core-periphery structure from east to west,which has direct effects and indirect effects on the spatial pattern of the producer service industry.Among the direct effects,comprehensive transportation accessibility has a stronger effect on the spatial pattern of producer services,and high-speed rail accessibility has a significant impact on the development pattern of producer services.In the indirect effects,accessibility has an important impact on the spatial pattern of producer services through factors such as spatial agglomeration,spatial competition,and market potential.3)The positive and negative effects of spatial agglomeration and spatial competition factors in neighboring counties on the spatial pattern of local producer service industries have increased.Market potential is the dominant factor in the location selection of producer service enterprises.Only when counties and districts have
