The financing lease method is that the Rail Transit Group transfers some equipment of the first phase construction of Rail Transit Line 3 to Kunlun Leasing Company at a price of 2 billion yuan, which is still used by the Rail Transit Group and pays rent to Kunlun Leasing Company on a quarterly basis. It is reported that the financing lease of 2 billion yuan will be used for the construction of rail transit line 3 currently under construction by Chongqing Light Rail Group. This can avoid taking up a lot of working capital because of equipment investment and revitalize enterprise assets.
