With the variance of regional policy of China, the city- regional development policy evaluation has experienced diversified systematical & methodological innovations in a cluster of explorative cases; nevertheless, there do exist deviations behavioral logic de facto and value benchmark of idealistic-orientation in the themed evaluation design. Under this circumstance, achieving the balance between instrument rationale and value rationale thus constitutes a new issue to be addressed confronting the researchers and practitioners. Based on field survey in Pearl River Delta region, this paper aims at pursuing an explorative comparative study on the fundamental stages of evaluation design— indicator selection and processing— for the purpose of utilizing statistics principles to identify and process the core value of evaluation indicators, with focuses on the data correlation of absoluteness and relativity as well as evaluation correlation of the “ought-to-be†approach and the de facto approach. To go further, it attempts to explore the impacts of various standardization methods on the comprehensive evaluation results, thus to forward the rationally feasible solution of indicator selection & processing with balance between behavioral logic de facto and value benchmark of idealistic-orientation. On this basis, the paper purses further comparative studies on the concluded benchmark indicator system of idealistic-orientation and the realistic evaluation system of Guangzhou’s new urbanization. In consequence, based on all the empirical research attained-above, the reasons for value absence in the city development evaluation are thus summarized, and the intrinsic motivation and the selection bias are anatomized correspondingly, eventually the paper attempts to forward several suggestions for maintaining the balance of the instrument rationale and value rationale in the construction of the city urbanization development evaluation system. |
