This research systematically compares the economic impact of different transaction methods for the entry of rural collectively-owned commercial construction land into the market (ERCCCLM) on the rural collective, and discusses how the rural collective can choose the appropriate transaction method in the process of land market reform. Based on rural collective-oriented economic analysis, various transaction methods are divided into long-term, short-term and mixed investment revenues, and the selection mechanism for ERCCCLM is proposed in combination with investment revenue demand. First, this research clarifies the current transaction methods for ERCCCLM based on regulations and policy documents, and determines the rural collectives' investment revenue calculation model for each transaction method. Meanwhile, based on the age structure of farmers in rural collective, set differentiated investment revenue demands for different types of rural collective. Then, the cumulative investment revenue rate changes of each transaction method over 40 years were estimated by normalization, which provides the basis for selecting the appropriate transaction method for different types of rural collective. The results show that short-term investment revenue transaction methods are more suitable for old-type rural collective, which means that farmers can obtain all investment revenue within a short period of time to avoid time restrictions on available revenue; Young-type rural collective can achieve sustainable accumulation of revenue and the possibility of higher revenue by adopting long-term investment revenue transaction methods; Adult-type rural collective can balance the diverse demands from different age groups through mixed investment revenue transaction method. The selection mechanism proposed in the research provides a systematic reference for screening suitable transaction methods for ERCCCLM based on the age structure of rural collective.
