摘要：长江经济带已经成为我国集聚效应辐射力很强的区域，成为我国实现空间经济发展的重要区域。物流产业对实现长江经济带区域间的经济互联互通发挥着重要的作用，成为长江经济带经济增长新的引擎。物流产业的集聚能够带来规模效应和经济效应，从而提高各区域的物流运行效率。近年来，长江经济带物流产业呈现了明显的集聚态势，而物流产业集聚的形成与一定的社会网络、社会关系和社会制度等社会资本密切相关，在这一背景下，研究长江经济带社会资本对物流产业集聚的影响，期望为政府制定区域物流协同发展政策提供科学依据。

主要研究内容：（1）长江经济带、物流产业集聚和社会资本的研究现状，物流产业集聚的概念、特征和主流理论，社会资本的概念、特征和构成。（2）长江经济带各地区物流产业集聚水平和社会资本水平的定量测度分析。（3）长江经济带物流产业集聚水平、社会资本水平的全局和局部空间自相关分析。（4）选取社会资本作为解释变量，测度的物流产业集聚水平作为被解释变量，基于长江经济带各地区2006-2015年的面板数据，应用空间杜宾模型探讨了社会资本对物流产业集聚的影响。（5）探究随着地理距离的增加社会资本的空间外溢效应所呈现的规律性。

主要研究结论：（1）长江经济带物流产业集聚水平和社会资本水平总体呈现持续的上升态势，但各地区发展存在明显的差异性。（2）物流产业集聚水平和社会资本水平相似的地区在空间上显著集聚，同时，社会资本通过空间外溢效应对周围地区的物流产业集聚发展产生显著的正向影响。（3）社会资本不仅对本地区的物流产业集聚水平存在显著正向影响，还通过空间外溢效应对周围地区的物流产业集聚水平产生显著正向影响。（4）社会资本的空间外溢效应存在一定的区域边界，在300公里以内显著，超过300公里不再显著。

ABSTRACT： TheYangtze River Economic Belt has become a region with a strong radiation effectof China's agglomeration effect, and has become an important region for Chinato realize the development of space economy. The logistics industry plays animportant role in realizing the economic interconnection between the regions ofthe Yangtze River Economic Belt and has become a new engine for economic growthin the Yangtze River Economic Belt. The agglomeration of the logistics industrycan bring about economies of scale and economic effects, thereby improving theefficiency of logistics operations in various regions. In recent years, thelogistics industry of the Yangtze River Economic Belt has shown an obviousagglomeration situation, and the formation of logistics industry agglomerationis closely related to certain social networks such as social networks, socialrelations and social systems. Under this background, the Yangtze River EconomicZone is studied. The influence of social capital on the agglomeration of logisticsindustry has important practical and theoretical significance.

The main research contents are as follows:(1) Research status of the Yangtze River Economic Belt, logistics industryagglomeration and social capital, the concept, characteristics and influencingfactors of logistics industry agglomeration, the concept, characteristics andcomposition of social capital. (2) Quantitative measurement analysis of thelevel of logistics industry agglomeration and social capital level in variousregions of the Yangtze River Economic Belt. (3) Global and local spatialautocorrelation analysis of the concentration level of logistics industry andthe level of social capital in the Yangtze River Economic Belt. (4) Selectingsocial capital as the explanatory variable, measuring the level of logisticsindustry agglomeration as the explanatory variable, based on the panel data ofthe regions in the Yangtze River Economic Belt from 2006 to 2015, using thespatial Dubin model to explore the impact of social capital on the logisticsindustry agglomeration. (5) Exploring the regularity of the spatial spillovereffect of social capital as the geographical distance increases.

The main research conclusions are asfollows: (1) The level of logistics industry agglomeration and social capitallevel in the Yangtze River Economic Belt generally show a continuous upwardtrend, but there are obvious differences in the development of various regions.(2) The areas where the level of logistics industry agglomeration and socialcapital level are similar are significantly concentrated in space. At the sametime, social capital has a significant positive impact on the development oflogistics industry in the surrounding areas through the spatial spillovereffect. (3) Social capital not only has a significant positive impact on thelevel of logistics industry agglomeration in the region, but also has asignificant positive impact on the level of logistics industry agglomeration inthe surrounding areas through the spatial spillover effect. (4) The spatialspillover effect of social capital has a certain regional boundary, which issignificant within 300 km, and more than 300 km is no longer significant.
