Based on the big data of 58 Anju platform，this paper analyzes the general rental housing market and long-term rental apartment market in China. The results show that in recent years，the overall number of floating population in China has decreased year by year，and the new tenants in the market，represented by the post-90s and post-95s，are more and more accepting of rental housing，and the demand for housing quality has also increased. Nationwide demand for rental housing is increasing year by year. In addition to the ordinary rental housing market for individual landlords，the long-term rental apartment market has gradually formed a market pattern with four major supply subjects：real estate brokerage agencies，Internet venture capital operation companies，hotels and real estate developers. However，there are still some problems in the current housing rental market，such as the decentralization of housing sources，the high proportion of spontaneous transactions between individuals，the difficulty in mastering the rental situation，and the lack of effective guarantee mechanism for the rights and interests of landlords and tenants. The standardization of the industry needs to be further improved. Therefore，we should further build a leasing service platform to record and supervise the rental houses；improve the access requirements of real estate brokerage institutions，enhance the qualification requirements of brokers，and strengthen the standardized management of large-scale leasing institutions；cooperate with internet platforms，especially vertical industry platforms，and increase the norms and constraints on the behaviors of both parties through market-oriented operation.
