中文摘要：

本文首先对全球价值链理论关于产业升级乐观论和悲观论的两种前景进行了回顾，并着重从空间关联维度剖析了该理论的不足。其次，本文对全球城市网络理论的命令控制和联系服务的两个分支进行了梳理，并侧重从产业关联维度挖掘了该理论的缺陷。在此基础上，本文梳理了全球价值链理论扣全球城市网络理论的交叉融合，并从发展中国家的现实状况和升级使命审视了两种理论在交融过程中所忽视的问题。本文最后指出，突破两种理论关于升级路径探究相对单一的不足后，发展中国家可以通过构建国内价值链和国内城市网络、发展先进生产者服务业来推进产城互动、协同升级。

英文摘要：

In the first place, this paper reviewed the two prospects of global value chain theory on the industrial upgrading＇ s optimism and pessimism, and emphatically analyzed the deficiency of this theory from spatial correlation dimension. Secondly, this paper made a review of the two branches of global city network theory on command control and connection service, and fo- cused on the defects of this theory from industrial correlation dimension. On this basis, this paper analyzed the cross integration of global value chain theory and global city network theory, and examined the problems neglected in the process of blending the two theories from the perspective of the reality and the upgrading of developing countries. Finally, after broking the shortage of relatively single discussion on the upgrading path of two theories, this paper pointed out that the developing countries can pro- mote the interaction and collaborative upgrading between industries and cities through the construction of domestic value chain, domestic urban network and develop advanced producer services.
