摘要: 在经济全球化、城市化的背景下,生产要素加速向大都市区聚集,包含多个城市群的经济带成为参与区域竞争的重要单元。基于2005~2014年长江经济带的数据,利用莫兰指数考察了交通基础设施和经济增长的空间相关性,结果表明存在显著的空间自相关,这可能得益于长江经济带发展较为成熟,已经初步形成综合性的交通网络,以及选取的省级研究尺度。接着建立了空间杜宾模型就交通基础设施对经济增长的影响进行了实证研究,结果表明前者对后者存在正的空间溢出效应,经济增长存在自身的空间溢出效应,这与理论预期、现实情况以及现有研究结论一致,忽略空间影响可能导致高估交通基础设施对经济增长的促进作用;劳动力和实际资本存量表现为促进经济增长,产业结构和政府支出则表现为抑制经济增长。长江经济带应进一步完善区域协同发展机制,加快推动交通基础设施互联互通,提高交通网络综合运行效率,提高劳动力利用效率,推动产业升级,同时避免过度的政府投资。

Abstract: In the context of economic globalization and urbanization, production factors increasingly agglomerates towards large metropolis. The economic belts that contain multiple contiguous urban clusters areimportantunits of regional growth and competition. This paper firstly uses the Moran’s Indextoexamine thespatial autocorrelationbetween transportation infrastructure and economic growth in the Yangtze River Economic Belt from 2005 to 2014. The results suggest that there is a significant correlation between transportation infrastructure and economic growth. One possible reason is that transportation infrastructure is relatively well developed in this broad region. The other is that it is appropriate to choose province as the studyarea. Moreover, using the spatial durbin model, this paper empirically analyses the impacts of transportation infrastructure on economic growth. The regression results indicate that transportation infrastructureis positively correlated to economic growth, andthe spillover of economic growth among regions are positive as well. These results are consistent with theoretical expectation and actual situation. Neglecting spatial interaction would result in the overestimation of transportation infrastructure’s effect on economic growth. What’s more, the labor force and actual capital stock are positively related to economic growth while industrial structure and government expand are negatively correlated with the dependent variable. Policy implications are the interprovincial collaboration in Yangtze River Economic Beltshould be further developed, the interconnectivityandeffectiveness of transportation infrastructure need improved. What’s more, it is necessary to increase the efficiency of labor force,promote theupgrading of industrial structure andavoid the excessive government investment.
