With the rapid development of economy and society, the competition in the real estate industry is becoming more and more severe. The core of the competition is to gradually improve the quality of differentiated products and save costs, which has formed a severe test for the cost management of real estate units. However, most of the real estate units spend most of their energy on the development and construction of new projects and ignore the cost control. With the introduction of national policies, the continuous standardization of the real estate market and the increasing number of competitors, the cost control of the real estate industry has become an important link. In recent years, the domestic supervision of the real estate industry has been strengthened year by year. The emergence of large-scale real estate groups has homogenized the real estate industry and gradually intensified competition, which has greatly reduced the profit rate of the industry. In modern economic society, the traditional cost control method has been unable to catch up with the development trend at any time. The use of modern new cost control methods and projects can not only reduce the cost. This can also improve the operation efficiency and save the activity cost of the company, because the company is very important in today's market environment, among which, the real estate enterprises play an important role in today's market economy, while the cost control management is very important in each, because only by strengthening the cost control of the real estate enterprises can the marketing revenue be increased. In order to maintain stability in the fierce social competition.
