In order to perfect the theory of regional Green GDP evaluation and facilitate the implementation of Green GDP evaluation, the regional Green GDP evaluation index system is constructed based on DPSIR model from five aspects: driving force, pressure, status, influence and response. SZ as an example to test the objectivity and operability of the index system, the use of entropy method to obtain the right of SZ green GDP evaluation index, the evaluation results are consistent with the reality of SZ. By case analysis, we can see that the index evaluation system based on DPSIR model is scientific and reasonable, but also operational
