An Empirical Study Of Real Estate Policy Impact On The Industry That Based On The SCP

China's real estate industry as an important industry to stimulate the growth of the national economy,its development history is short,and the development way also has certain uniqueness.And compared to other developed countries that the real estate industrythrough the development process improvement,the real estate industry in China has the characteristics of the late development,the system development is not perfect,and the economy is impacted by the economic transition.In the process of self-regulation of the market also had a lot of problems,which need the government to manage and regulate effectively.At the same time our Government received some success in the macro-control of real estate industry,it should also be noted that the housing supply structure is irrational,the supply and demand structure is not balanced,and other aspects of the problem.In order to draw on the existing policy experience,to improve the follow-up of the macro-control policy,our government need to conduct an in-depth analysis in the real estate policy implications and regulatory effect,to carry out an objective evaluation.This paper aims to construct the frame of SCP paradigm of real estate industry,analyze the influence of real estate industry macro control,establish the structure of policy influence analysis of structure-behavior-performance,and finally evaluate the overall effect of macro-control policy.Propose appropriate policy recommendations based on the results,in order to provide a reference direction to improve our government's macro-control of real estate.In this paper,Granger causality test is used to analyze the influence of policy on the components of real estate SCP.Based on the empirical results of Granger causality test,this paper summarizes the policy implications of various parts of industrial organization framework.In the market structure,the impact of financial policy on the land price and policy expectations there is a certain deviation;tax policy in the short term did not have a significant impact on the land transaction price;land policy in the adjustment of land new construction area does not meet the expected impact of the policy.In order to control the supply of land,the government should pay attention to the reasonable planning of the scale of housing supply and use the tax and financial policies to regulate the actual supply of ordinary housing land,to curb speculative demand.In the market behavior,the tax policy has a significant impact on the housing sales price;the financial policy does not have a significant impact on the housing sales price,and the land policy and financial policy play a slower effect.In the regulation of house prices,the government should pay attention to strengthen the financial and land policy classification control effect,combined with the actual situation to play a policy effect.In the market performance,financial policy on the impact of short-term sales investment ratio does not significant;the long-term impact of tax policy is significant,only in the short term did not have a significant impact on the completion of investment;land policy on the proportion of affordable housing area does not have a long-term impact.The government should expand the supply of ordinary housing land,combined with preferential tax policies to promote the supply of affordable housing,and pay attention to enhance the relevance of financial policy to promote a virtuous circle of enterprise capital chain.Combined with the above analysis,this paper summarizes the various parts of the industrial structure according to the macro-control objectives of real estate,and constructs the evaluation index system of real estate industry policy.Using principal component analysis,this paper evaluates the actual effect of China's macro-control in real estate in recent years.The results show that China's policies in balancing housing market,preventing overheating investment and restraining property prices are pointed and sharp,but there are some problems such as uncoordinated policies and measures.Finally,in view of these problems,this paper puts forward four policy suggestions: increasing the effective supply of land,perfecting the land planning and utilization;implementing the differential credit policy,improving the supervision;adjusting and perfecting the taxation policy,restraining the speculative demand of the real estate industry;build long-term regulation of real estate industry,maintaining the consistency of policy implementation.
