The community-based rural planning emphasized adopting participatory processes for community autonomy but frequently resulted in poor efficiency. However, many governments still encourage the method of community-based rural planning. This represents the method is appropriate but must improves its inefficiency problem of rural planning. The purpose of this article is to examine the efficiency of community-based rural planning, and further to understand the relationships between the variables of rural communities and the planning efficiency and the improving strategies in the future. This article used regression models to analyze 150 rural communities in Kobe city in Japan. We found that to improve the planning efficiency was obviously more important to promote the "industry operation" concept than the "environmental resources" concept. For concept of "environmental resources", the results presented the significantly negative relationship between the variable of "densely inhabited district time (DID)" and the time consumption of rural planning. As for "agricultural industry operation" concept, the results showed the significantly negative relationships between the variables, i.e., "number of legal person organization" and "income size of undertaking", and the time consumption, and showed the significantly positive relationships between the variables, i.e., "no cooperation proportion" and "number of wholesale" and the time consumption. This article clarifies that the community-based rural planning is rather time-consuming and suggests that the strategy to enhance efficiency of rural planning must elaborate to improve the autonomic capacity of community-based operation rather than to be dominated by the organizations of wholesales. The results provide experiences to promote rural planning efficiency for policy of rural regeneration in Taiwan.
