For a long time, the current mechanical equipment of the construction site is subordinate to the construction enterprise, which aims to serve the construction of the enterprise, resulting in the situation of low utilization rate of mechanical equipment and poor investment effect. At the same time, the mechanical equipment purchased by each enterprise is almost similar, and the repeated investment is serious, resulting in a serious backlog of social assets. The serious aging of mechanical equipment, the large amount of idle equipment has become a heavy burden for construction enterprises, limiting the development and progress of mechanical equipment. After the establishment of socialist market economy system, we must pay attention to the investment benefit of equipment. In order to socialize the construction machinery, it is necessary to establish the social rental market of machinery and equipment as soon as possible, so as to activate the fixed assets of machinery and equipment, reflect the investment effect, improve the utilization rate of machinery and equipment, and realize the purpose of machinery renewal. The establishment of social rental market of mechanical equipment can improve the management, use, maintenance and repair level of mechanical equipment, reduce consumption, save human, material and financial resources, carry out technical training and international exchanges, and improve their own quality.
 
However, due to many factors, the development of mechanical equipment leasing industry is seriously restricted.
 
(1) the macro management of leasing industry lacks a unified centralized department.
 
At present, the leasing industry is under the management of the Ministry of foreign trade and economic cooperation, the people's Bank of China, the State Administration of foreign exchange, the State Administration for Industry and Commerce and other departments. Due to the decentralization of power and unclear responsibilities, it is easy to produce the phenomenon of mutual friction and mutual prevarication. It is difficult to coordinate and unify policies, which makes the management of the leasing industry in China fall into a "vacuum zone" with no real name. On the contrary, there is no Leasing Industry Association in China that has close contact with the competent government departments and coordinates, guides, communicates and serves the business management and information of leasing companies.
 
(2) the lack of leasing laws and regulations to protect the normal development of the leasing industry, resulting in the long-term "no basis, no rules to follow" environment.

At present, there is not a systematic and complete leasing law to protect the legitimate rights and interests of leasing parties. Only in the economic contract law, the general principles of civil law, the relevant documents of the Ministry of Finance and the Interim Measures for financial leasing formulated by professional banks, there are some simple provisions, which are far from meeting the needs of the reality of the leasing industry. The leasing industry can not be relied on, the parties to the leasing contract do not have a unified code of conduct, and the legitimate rights and interests of the leasing contract are difficult to be effectively protected. In project bidding and credit review, the legitimacy of leasing industry has not been protected, which seriously hinders the normal operation and healthy development of leasing industry in China.
 
(3) lack of financial and tax policies to support the development of leasing industry.
 
In order to support the development of leasing business in foreign countries, most of them adopt preferential financial and tax policies. In China, leasing financing is regarded as loan for a long time. In terms of tax revenue, it is the same as general commercial behavior. General banks do not accept mortgage loans and bank credit guarantees of leasing industry, and insurance industry does not participate in the insurance work of leasing industry, which has become an obstacle to the normal development of leasing market.
 
(4) at present, the type of leasing business is relatively single, which is basically limited to general import finance leasing and concurrent physical leasing.
 
financial leasing, such as leaseback, export leasing and other businesses are almost not carried out. In the physical leasing business, it is seldom to carry out the business of leasing and selling on behalf of others. There are many reasons for the single form of leasing, such as the shackles of the state-owned assets management system, the non matching of the seller's credit and credit insurance, the credibility of the leasing media and the fear of risks of the state-owned economy. Obviously, the phenomenon that the manufacturer only sells but does not rent has a significant gap with the similar foreign enterprises. These reasons have restrained the development of diversified leasing forms in China.
 
(5) the rent arrears are very serious, which makes the capital turnover of the leasing company difficult.
 
According to relevant data, by the end of 1994, 17 Sino foreign joint venture leasing companies were in arrears with rent of 600 million US dollars. The large amount of rent in arrears makes the leasing companies fall into serious operating difficulties. With the establishment and gradual improvement of China's market economy system, it is believed that China's leasing industry, as a new industry, will surely shoulder the historical responsibility and continue to grow.
