Abstract: Based on the existing research, the research on cluster upgrade is usually at the angle of simple localization, globalization, or the interaction between two of them. An unique and innovative perspective based on localization, regionalization and globalization of space integrated cluster is adopted, and economic geography, industrial economics, and regional economics are also comprehensively used, the multi-cluster update mechanism based on multiple-layer space integration is revealed and discussed; on the basis of the analysis on cluster localization, regionalization, and globalization means and natural evolution of upgrading space, the multi-level space-based model and upgrade path of both endogenous and exogenous types clusters are extracted, respectively. The results not only expand the research area on the upgrade of the local industry cluster, but also provide a new method for local governments to develop and implement policies related to cluster upgrades.

Key words: localization, regionalization, globalization, space integration, cluster upgrade, industry force
