In this paper, the practice of the past 30 years of reform and open policy was analyzed. A comprehensive evaluation model based on Analytic Hierarchy Process (AHP) was established and some empirical analyses (data from 1978-2006) on the rural construction were made based on this model. It is concluded that the rural construction has achieved the great success since carring on the reform and open policy. The rural construction during this period could be divided into two stages. At the first stage, achievements were mainly due to the construction of agricultural development and rural harmony-driven. And at the second stage, achievements were mainly due to the improvement of the quality at present. Consequently, the efforts to improve the rural construction must be intensified for a long time. Moreover, it is necessary to grasp the key points to make up the lack of rural construction. 展开更多
