The implementation of open government data policies at the local level is a complex system issue given no universally applicable promotion model. In order to systematically discuss the policy instruments selection strategy for local governments, based on the two-dimensional analysis framework of policy instruments of the open government data ecosystem, using content analysis, hierarchical clustering, and co-occurrence analysis, this paper first performed tool coding and quantitative analysis on the local government open data policy text, and differentiated the instruments application status and regional differences in terms of instrument and stage dimensions; secondly, it revealed preferences ofthe local government onpolicy instrument application and characteristics of instrumentcombination used by local governmentby means of city cluster analysis and tool combination co-occurrence analysis; finally, it summarized the typical strategy of how local governments select open data policy instruments.
