The purpose of this paper is to establish a feasible evaluating indicator system for assessing real estate investment environment based on the statistical data in the selected 12 cities in Hubei. Methods of OLS, principal component analysis and Cluster analysis were employed The results indicate that： （1） The evaluating indicators of real estate investment environment have been chosen based on 5 aspects, i.e., natural environment, macro-economy, real estate market, infrastructure, social and cultural. （2） The advantages and disadvantages of investment environments in sampling cities have been analyzed using OLS and principal component method. （3） The blindness in selecting the indicators has been avoided. （4） By using OLS method, the weights of various indicators are determined, and the niche evaluation formula of real estate investment environment has been established.（5 ~hrough previous steps the comprehensive scores about real estate investment environment of 12 cities have been calculated. （6） Using cluster analysis method for classification and grading of the city and proposing optimization strategy from the perspective of niche. It is concluded that the established evaluation system of real estate investment environment has good logicality, and the evaluating method is concise and highly effective, and has considerable practical value
