随着工业化、城市化及全球一体化进程的加快，城市间密切的联系在区域经济增长中发挥着重要作用。“中四角”具备天然的地域联系，同时拥有良好的经济形势、政策保障及便捷的交通网络，联动共建基础坚实。以“中四角”的核心城市作为研究对象，通过区位熵判断城市的优势产业，运用城市流强度等指标确定四城市的外向程度，并根据综合交通可达性测度各个城市的交通发展状况。研究表明，合肥、武汉、长沙、南昌产业发展各有特色，但存在一定的产业趋同现象；长沙的外向程度相对较高；武汉的交通通达性最佳，而合肥、南昌虽有一定的外向经济和综合运输体系，但整体上仍处于“中四角”发展的末端。在此基础上，提出加强空间联系、推动“中四角”城市建设的有效举措，以期为“中部崛起”的实施提供实践支持。

With the acceleration of industrialization, urbanization and global integration, the connection between cities is becoming increasing intimate, which plays an important role in regional economic growth.“Four-city Area in Middle China”enjoys a nature areal association, together with favorable eco-nomic situation, policy guarantee, convenient traffic network and solid foun-dation of linkage co-building. Taking core cities in “Four-city Area in Mid-dle China”as study objects, the author made a judgment of competitive indus-tries in each city by using location quotient, figured out the extroversion degree through some indexes, such as urban flows, and then measured the traf-fic development situation according to comprehensive traffic accessibility. Several conclusions can be drew from the paper: firstly, industry development in four cities have their characters respectively but an industry convergence still exists; Secondly, Changsha holds the highest extroversion degree;Thirdly, Wuhan is equipped with the best traffic accessibility, with Hefei and Nanchang stand at the end of “Four-city Area in Middle China”, although both of them have an outward-looking economic system and comprehensive trans-portation system. Based on these, the author suggested that strengthen the spatial connection and promote city construction of“Four-city Area in Middle China”could be a practical support for implementing the rising strategy of Central China.
