为促进区域交通枢纽与经济的协调发展，研究了区域交通枢纽与经济发展水平的适应度。首先，建立交通枢纽与经济交互作用下的两个子系统，然后选取交通枢纽与经济相关指标，构建适应度评价函数，进而评价交通枢纽与经济发展的适应情况。以九龙坡区为研究对象，将2008—2015 年交通枢纽与经济基础数据转化为其增长率，然后对二者综合发展水平进行了计算，根据适 应度模型对二者之间的适应度进行测算。结果显示，经济综合发展水平略大于交通枢纽发展水平，二者之间适应度经历“S”型周期波动变化过程，且适应度值整体处于0.4 以上，均未达到较强的适应状态。在未来经济发展中，交通枢纽建设有待加强，而且需占主导地位，才能引导经济 快速发展。

In order to promote the coordinated development of regional transport hub and economy, the adaptation degree of regional transport hub and economy development level was studied. Firstly, two subsystems based on the interaction regularity between transport hub and economy were established. Then indicators related to transport hub and economy were selected to construct the adaptation degree evaluation function, the adaptability of transport hub and economy development was evaluated further. Taking Jiulongpo District as the research object, annual basis data of transport hub and economy from 2008 to 2015 was converted into the growth rate. Then the comprehensive development levels of both transport hub and economy were calculated, the adaptability between the transport hub and economy was calculated according to the adaptation degree model. The results show that the comprehensive development level of the regional economy is slightly larger than that of the transport hub, the adaptation degree of the two has experienced a "S" cycle dynamic change process, and overall adaptation degree value is 0.4 or more, which doesn′t reach the strong state of adaptation. In the future economy development, the construction of transport hub needs strengthening, and should occupy the dominant position, so as to guide the rapid economic development.
