2019 is a year of rapid development of regional integration in the Yangtze River Delta，which has injected vitality into the development of the real estate market. In the whole year，the real estate market in major cities showed a trend of continuous recovery，with the volume of housing transactions in most first tier and second tier cities rising and prices stabilizing. The ripple effect of housing prices in urban agglomerations is obvious. Prices are mainly driven by second tier cities. Hefei，Jiaxing，Suzhou，Wenzhou，Wuxi and other cities have a greater impact on housing prices in surrounding cities. The transaction volume of land market is enlarged，and the housing supply is expected to increase in the later period. The rental market in Shanghai has experienced adjustment and the rental price has declined. The real estate market regulation and control policies in major cities began to increase，but the housing policies for talents in some cities also increased. It is predicted that the real estate market in the Yangtze River Delta will develop steadily in 2020，and the uncertain impact of economic growth will be relatively small，but the probability of cold and hot differentiation of the real estate market in the third and fourth tier cities will increase.
