摘　　要：区域多样化发展在提高生产力、促进就业以及稳定经济等方面发挥着重要作用。一直以来演化经济地理学框架下区域多样化发展中外部资源的作用被忽略,而跨区域合作创新是区域获取外部知识的重要途径之一。研究使用2000~2017年长三角地区41个城市的发明专利数据,对区域经济一体化特征显著的长三角地区多样化水平与合作创新进行测度,并实证检验区域内部与跨区域的合作创新在区域多样化进程中所发挥的作用。结果表明:(1)长三角地区各城市的相关与不相关多样化水平总体呈现逐渐上升并趋于稳定的趋势;(2)合作创新作为知识流动的重要载体,合作参与者大多位于长三角内,合作创新所产生的知识溢出往往发生在具有技术关联性的产业间,从而有助于促进长三角地区发展相关多样化,但对不相关多样化没有表现出显著影响;(3)合作创新中参与团队数量与区域相关与不相关多样性没有显著关系;(4)合作创新中跨区域合作比例越高,越能够促进区域相关与不相关多样化的发展。因此,在推动区域产业多样化的过程中应注重强化区域间的合作,借助外部力量引导区域产业发展。Regional diversification development plays an important role in enhancing productivity, promoting employment and stabilizing the economy. Regional industrial change is largely understood by evolutionary economic geographers as an endogenous phenomenon so far and the role of external resources in regional diversification development has been neglected. Actually trans-regional cooperation innovation is one of the important ways to obtain external knowledge in the region. Although many studies have confirmed the positive impact of extraregional knowledge inputs on innovation, the impact of these innovations on regional industrial continuity and change is rarely mentioned. Using the invention patent data of 41 cities from 2000 to 2017, this study measures the diversification level and cooperative innovation in the Yangtze River Delta which has a significant regional economic integration characteristics, and empirically tests the role of intra-regional and inter-regional cooperative innovation in the process of regional diversification. The results show that:(1) The level of related and unrelated variety of cities in Yangtze River Delta generally increases gradually and tends to be stable, With the development of economy, the diversity of cities is gradually narrowing;(2) Cooperation innovation is an important carrier of knowledge flow. Out-of-area cooperation patents are dominated in the Yangtze River Delta region, that is the proportion of participants in the city of cooperation patents is generally smaller than that of participants in other cities, while participants outside the city are mainly located in the Yangtze River Delta region. Cooperative innovation contributes to the development of related variety in Yangtze River Delta, but has no significant impact on unrelated variety;(3) The number of participating teams in cooperative innovation has no significant relationship with regional related and unrelated variety;(4) The higher the proportion of inter-regional cooperation in cooperative innovation, the more r
