政治经济学视角下我国生产性服务业发展的多层级动力机制及其区域城市化效应

作为具有最先进知识和技术的"中间投入品"为各产业部门提供专业化服务，生产性服务业已成为"后工业社会"区域经济和城市体系重构的主导产业部门，其空间分布结构和增长动力一直以来都是城市和经济地理学家关注的热点议题。现有研究大多关注产业集群、空间集聚效应和地方化的生产网络等市场机制的影响，相对忽视了政府这一非市场化的行为主体在生产服务业空间演变中的重要性。在我国这样一个政府强权的政治经济体系中，对政府角色和作用的研究不足有碍于我们深入理解生产性服务业发展的本质和内涵。本项目以正在经历由"世界工厂"向新兴产业转型的珠江三角洲为实证研究地区，基于政治经济学的理论框架，分析不同市场化程度的生产性服务业部门的空间分布格局，探讨生产性服务业发展的多层级动力机制，以及揭示生产性服务业的产业联系及其空间结构对区域城市化进程的影响，为优化区域城镇体系的空间结构和提高区域的空间管治能力提供理论依据和参考。

Providing intermediate inputs throughout the value chain and supplying state-of-the-art knowledge and expertise, producer services have been identified as the lead sector shaping urban-regional economies in "post-industrial societies". Their spatial development and underlying processes have long been a topic attracting the attention of urban and economic geographers. Existing literature has focused on industrial clustering, advantages of agglomeration economies and localized production network, but relatively less studied the role of the state. This has become increasingly inadequate to understand the nature of the growth and location of producer services in China where the state is powerful in intervening in the economy. Drawing upon the theoretical framework from state-market relation/interaction, this proposed research will take the Pearl River Delta, where significant economic transformation is occurring, as a case to analyze the spatial patterns of producer services with different levels of marketization, probe into the multi-scalar growth dynamics of producer services, and investigate the regional linkages of producer services and their urbanization effects. It will provide solid theoretical foundation for the improvement of urban spatial planning and governance.
