Evaluation of Public Policy Effect of Urban Land Market under Major Events——An empirical study based on 35 large and medium-sized cities
In this paper,the seasonal adjustment method and HP filtering method are used to measure the impact of major pub-lic health events in the theoretical model by using 21 quarterly income data of 35 municipal governments,enterprises and residents.In addition,the breakpoint regression method is used to empirically test the impact of public policy on land price under major public health events,and further stability test and heterogeneity test are carried out through zoning and stratification.The results show that major public health events still cause large fluctuations in the three sectors in the short term,among which the real estate enterprise sector has the largest short-term fluctuation and has a significant destructive effect on the urban land market.The public policy has re-vised the urban land market,but it decreases with the increase of the impact degree,and the policy effects on different regions,differ-ent cities and different land use markets are also different.The conclusion of this paper provides a quantitative judgment for deepening the evaluation of public policy effects of urban land market under major events,and provides some theoretical support for government departments to formulate more accurate and effective public policies for urban land market.
