Abstract:Green innovation is the effective?approach to?solve the problem of the economic?development, environmental protection and social?harmony. The establishment of the index system is an important?part?of the?comprehensive?evaluation?for?the green innovation capability about the resource-based cities. Based on the typical high-frequency indictors from the?foreign and domestic?literature, this paper selects 70 indicators and the observed?data under the connotation?of?green innovation capability?.After normal?distribution of date, the paper screens the indicators with the gray relational analysis method and spearman rank?relational?coefficient method. It guarantees that the screened indicators have little duplicate?information and significant effect on results. At the same time, it avoids the disadvantage that ignores the?conditions of screening methods before using in existing?research. The index system contains 27 indicators with 10 typical resource-based cities in 2016,which confirms the feasibility and effectiveness of this method.Finally, the?paper puts forward?some?policy.
