The reporter learned from the Ministry of housing and urban rural development that in 2021, 40 cities across the country plan to raise 936000 new affordable rental housing units. Among them, 720000 units have been started from January to September, accounting for 76.9% of the annual plan, with an investment of 77.5 billion yuan. Nanjing, Wuxi, Ningbo, Foshan, Changchun and Nanning have completed their annual plans. Relevant people said that accelerating the development of affordable rental housing will help new citizens, young people and other groups alleviate housing difficulties and promote a new type of urbanization with people at the core. The source said that at present, the key and difficult point for all people to live is new citizens and young people. Accelerating the development of affordable rental housing with small house type, low rent and conducive to the balance of work and housing can effectively help new citizens, young people and other groups to alleviate phased housing difficulties. The source pointed out that accelerating the development of affordable rental housing can effectively increase the supply of small households (including dormitories) and low rent houses, optimize the supply structure of rental housing and make up for the shortcomings of rental housing. At the same time, through government policy support, effectively revitalize the use of various land and housing resources such as collective operational construction land, self owned idle land of enterprises and institutions, supporting land in industrial parks, stock idle houses and newly supplied state-owned construction land, guide various subjects to invest in construction, and promote the simultaneous development of multi-agent supply, multi-channel guarantee and rental and purchase. In fact, Beijing made it clear that the housing security system consists of public rental housing, indemnificatory rental housing and common property housing. Shanghai has made it clear that the housing security system takes indemnificatory rental housing and common property right housing as the main body. Shenzhen will adjust the current public housing composed of public rental housing, talent housing and secure commercial housing to a housing security system composed of public rental housing, indemnificatory rental housing and common property housing. In this context, affordable rental housing has become the key task of housing construction during the 14th Five Year Plan period. Recently, the opinions on accelerating the development of indemnificatory rental housing issued by Wuhan city put forward that during the 14th Five Year Plan period, the city plans to build and raise 250000 sets (rooms) of indemnificatory rental housing. During the 14th Five Year Plan period, Shanghai plans to add 470000 affordable rental housing units (rooms), 600000 units (rooms) in Guangzhou and 400000 units (rooms) in Shenzhen, all accounting for about 45% of the total new housing supply. Beijing is preparing the "14th five year plan" for housing development, in which affordable rental housing will account for no less than 30%. During the 14th Five Year Plan period in Hangzhou and Xi'an, it is planned to add 300000 indemnificatory rental houses, 250000 in Chengdu and Xiamen, and 200000 in Ningbo and Foshan. (outlook new era)
