首先，大家很明显的可以看出，资产的优化大力培植了租赁业的规模。许多工程机械的专业化程度很高，其功能与使用范围有很大的局限性。一种施工机具只能完成某一项特定作业，不同的工程项目，要有不同的设备配套方案，因此会造成设备的闲置和利用率不高，制约了施工企业的经济效益。
First of all, we can clearly see that the optimization of assets has vigorously fostered the scale of the leasing industry. Many construction machinery have high degree of specialization, and their functions and application scope have great limitations. A construction machine can only complete a specific operation. Different engineering projects need different equipment matching schemes. Therefore, the idleness and utilization rate of equipment is not high, which restricts the economic benefits of construction enterprises.
对于整个社会来说，这就造成了很大的资源浪费。租赁业可以在许多工程承包商之间起到一种调剂作用，盘活闲置设备，优化社会存量资产，有利于拉动社会投资，是促进资金和设备流通的重要手段。对于独立的租赁公司，租赁业务为资金市场找到了新的途径，使死钱变活钱，是种很有前途的投资方式。
For the whole society, this has caused a great waste of resources. The leasing industry can play a mediating role among many project contractors, activate idle equipment, optimize social stock assets, help to stimulate social investment, and is an important means to promote the circulation of funds and equipment. For independent leasing companies, leasing business has found a new way for the capital market to make dead money live money, which is a promising way of investment.
