The research constructs the collaborative agglomeration index of producer services and manufacturing industries. Based on the data of prefecture level cities in the Yangtze River Economic Belt, this paper analyzes the spatial pattern evolution and its driving mechanism. The research shows: The high collaborative agglomeration index areas of producer services and manufacturing industries showed the spatial characteristics that downstream of the Yangtze River Economic Belt is as the core and gradually transits to the middle reaches of the Yangtze River, and the middle uplifts; The overall performance of the spatial trend is that "northeast is high, central uplifts, southwest is low"; The development of collaborative agglomeration presents a continuous spatial agglomeration trend, and the agglomeration strength showed a rising trend of "W". There is a significant hot spots area of high value agglomeration and cold spots area of low value agglomeration; Collaborative cluster has an obvious spatial spillover effect, government behavior, urbanization, market driven, innovation ability, internet technology and infrastructure has a significant and positive influence to collaborative agglomeration, the government behavior is relatively large, but the intensity of Internet technology and infrastructure is relatively weak.%研究构建了生产性服务业与制造业协同集聚指数,利用长江经济带地级市数据,分析了其空间格局演化及其驱动机制.研究得到以下结论:生产性服务业与制造业协同集聚高度区域表现出以长江经济带下游为核心逐渐向长江中游过渡,且中游隆起的空间特征;整体表现出"东北高,中部隆起,西南低"的空间趋势;协同集聚发展呈现了持续的空间集聚态势,且集聚的强度呈现出波动上升"W"的变化趋势.协同集聚存在显著的高值聚集热点区和低值聚集冷点区,协同集聚存在明显的空间溢出效应,政府行为、城镇化、市场驱动、创新能力、互联网技术与基础设施均对协同集聚具有显著的正向影响,其中政府行为的影响程度相对较大,但是互联网技术和基础设施的作用强度还比较微弱.
