Abstract: 【Purpose/significance】Constructing scientific ecological data evaluation model is an important content of ecological civili⁃
zation construction. It is necessary to start with pertinence and rigor to summarize and analyze the data to provide strong data support
for improving the accuracy of the evaluation system.【Method/process】Taking China's inter-provincial ecological index as an exam⁃
ple, this paper uses entropy method to optimize the evaluation index. Through data model construction and weight measurement, the
data indexes that can scientifically and accurately evaluate China's current ecological civilization construction status can be screened
out from the massive data.【Result/conclusion】The evaluation model based on entropy value method reasonably solves the problem of
inaccurate evaluation system evaluation and does not accord with the reality, shows the situation of inter-provincial ecological develop⁃
ment, and puts forward the solution to the evaluation problem of inter-provincial ecological development in China. The empirical re⁃
search results show that the evaluation method is scientific.【Innovation/limitation】This paper uses the improved entropy method to
obtain the data evaluation model of China's inter-provincial ecological index, which can be used for subsequent comprehensive evalua⁃
tion. In view of the availability of data, some studies adopted numerical simulation methods to improve the econometric model analysis
in the future and further improve the precision of the results.
