【摘要】 文章深入探究江西自唐以降步入千年辉煌期以及在近代经历百年衰落的历史轨迹，着重阐释“赣江—鄱阳湖水道”（以下简称“赣鄱水道”）变迁在其中的关键作用与深远影响。唐宋时期，“赣江—鄱阳湖水道”的开通，重塑了江西的交通格局，有力推动了区域间的经济、文化交流，成为江西走向繁荣的重要驱动力。近代以来，海运兴起和铁路等现代交通方式的发展，该水道的优势逐渐削弱，成为江西衰落的重要交通因素。在此基础上，文章进一步探讨内陆省份区位特点与区位优势转化机制。通过对江西不同历史发展阶段的分析，揭示出其内陆省份区位特点在交通网络完善、区域经济联系紧密等条件下，能够转化为显著的区位优势；反之，在交通格局变革中若不能及时适应，则易转变为区位劣势。更多还原

【Abstract】 This paper deeply explores the historical trajectory of Jiangxi’s entry into a millennium of glory since the Tang Dynasty and its experience of a century of decline in modern times. It focuses on explaining the crucial role and far-reaching impact of the changes in the “Waterway of Ganjiang River-Poyang Lake” in this process. During the Tang and Song dynasties, the opening of the waterway reshaped Jiangxi’s transportation pattern, effectively promoted economic and cultural exchanges among regions, and thus became an important driving force for Jiangxi’s prosperity. Since modern times, with the rise of maritime transportation and the development of modern transportation modes such as railways, the dominant position of this waterway has gradually weakened, which has become an important transportation factor in Jiangxi’s decline. On this basis, this paper further explores the transformation mechanism between the location characteristics and location advantages of Jiangxi as an inland provinces. Through the analysis of different historical stages of Jiangxi, it reveals that under the conditions of a complete transportation network and close regional economic connections, the location characteristics of an inland province can be transformed into significant location advantages. Conversely, if they cannot be adapted in a timely manner during the transformation of the transportation pattern, they are likely to turn into location disadvantages.更多还原
