The real estate industry is not only a comprehensive industry, but also a resource integration industry. From project planning, design, construction, landscape, decoration and property management, procurement activities run through the whole business process and occupy an important position in the real estate industry chain. Suppliers have become an important extension of the core value of real estate enterprises. In a sense, the competition among real estate developers will be the competition of supply chain. With the gradual disappearance of land dividends and financial leverage, the development cost of real estate enterprises remains high, and the profit rate of the industry declines. Supply chain will become a key factor restricting the healthy and rapid development of real estate enterprises.
