中文摘要：

以经济、空间和制度为基点,构建了西北内陆城镇密集区整合发展的理论框架。进而,以兰州——西宁这一典型的西北内陆城镇密集区为例,在此理论框架内探讨了整合发展的基础条件、制约因素和内外动力,并最终总结出不同阶段的经济、空间和制度整合模式。其中,经济方面包括产业互补模式、雁行发展模式和经济一体化模式,空间方面包括双核整合模式、轴线整合模式和面域整合模式,制度方面包括对宏观制度和微观机制的创新变革。

英文摘要：

Choose the economy, space and institutionas three integration basic-points, and elementarily construct the theory frame on integration development of northwest interior CCAs. Then, the paper takes Lanzhou-Xining CCA as a typical case, and analyzes its basic terms, restricting factors, inner and outer dynamics under the theory frame. Lastly, the paper summarizes the economic, spatial and institutional integration models at different stages. Among them, the economic models include mutual complementary industry model, flying geese development modeland economy integration model. The spatial ones include dual-core, axes and polygon integration models. The Institution ones include innovations of macroinstitution and microcosmic mechanism.
