Research On The Evaluation Of Real Estate Investment Efficiency Under Supply Side Reform

As a pillar industry that enhances China's national economy and improves people's lives,the real estate economy also occupies an important position in China's economic aggregate.In recent years,China's real estate development investment growth rate and its contribution rate to GDP have shown a downward trend.Some real estate development enterprises pay less attention to improving their efficiency and competitiveness in their business activities.The development of the industry is an extensive extension.The road to expansion.The Party Central Committee and the State Council attach great importance to the structural optimization of the supply side and the sustainable development of the real estate market.The supply-side reform of the real estate market can expand effective investment and improve investment efficiency,and it has important theoretical and practical significance for realizing the precise regulation of the real estate market and promoting its long-term sustained and steady development.This paper takes real estate investment efficiency as the research object.Under the policy of supply-side reform,it sorts out the current situation and existing problems of real estate investment in Xi'an,establishes the evaluation index system of real estate investment efficiency,and optimizes it by principal component analysis.Finally,a comprehensive evaluation model of real estate investment efficiency was constructed,aiming to provide better scientific reference and theoretical basis for improving the efficiency of real estate investment,to regulate the unbalanced structure of supply and demand imbalance in the real estate market,and to promote the long-term and stable development of the real estate industry.The research results show that the efficiency of real estate investment in Xi'an has increased year by year in the past 10 years,but the technological progress effect and scale effect have not reached equilibrium.The invalidity of scale efficiency is the main reason for the inefficiency of comprehensive investment in real estate.There is still much room for improvement in enhancing the awareness of high efficiency and strengthening technological innovation,which is in line with the development of real estate investment in Xi'an.The innovation of this paper is to focus on the supply-side reform and focus on the specific research of the region.The effectiveness of the traditional DEA method will be affected by the number of indicators and their correlation,so a comprehensive evaluation model of super-efficient SBM-Malmquist real estate investment efficiency based on principal component analysis was established to evaluate and improve the efficiency of real estate investment in Xi'an from the static and dynamic perspectives.
