以产业创新完善流通节点城市功能，进而带动区域经济增长是构建西部陆海新通道的内在要求，但是创新基础各异的沿线城市其功能分工是否有助于区域经济增长有待验证。本研究以西部陆海新通道沿线12个枢纽城市2007-2018年的城市数据为样本，从产业创新管理视角进行实证研究，结果发现：西部陆海新通道沿线枢纽城市的功能分工与区域经济增长存在正“U”型的非线性关系，但目前通道沿线多数枢纽城市均处于功能分工拐点的左侧；鉴于北线枢纽城市功能分工水平总体上优于南线枢纽城市，按目前趋势，未来北线枢纽城市的功能分工将早于南线枢纽城市对区域经济增长起到正向促进作用。

To improve the function of circulation node cities by industrial innovation and then drive regional economic growth is the inherent requirement of building a new channel of land and sea in Western China,However, whether the functional division of cities along the line with different innovation bases contributes to regional economic growth remains to be verified.Based on the data of 12 hub cities along the new road from 2007 to 2018, this paper makes an empirical study from the perspective of industrial innovation management,the results showed that: There is a positive "U" type nonlinear relationship between the functional division and regional economic growth of the hub cities along the new land sea corridor in Western China,but most of the hub cities along the corridor are on the left side of the inflection point of functional division;In view of the function division level of the north line hub city is better than that of the south line hub city,according to the current trend, the functional division of the North hub city will be earlier than that of the southern hub city in the future, which will play a positive role in promoting regional economic growth.
