Loan platforms set up by local governments are doing a construction business with financial loans from banks instead of government themselves. Loan platforms can be classified by unit model, multi model and 1+N model. Some studies argued Shanghai model, Chongqing model and Sichuan model etc., however we cannot classified over Chinese ten thousands platforms into several name of cities. The unit model is a common type of loan platform and would set up by any level of local government regardless their size. Also it has low debt ratio and low possibility making bad loans. Multi model is suitable method for big cities which want to do operating large projects. A local government set up lots of construction companies and operates many projects in same time. However in this type is easily making bad loans like Chongqing case. Final type of loan platform is called 1+N model. In case of local government do not have enough budget to do multi projects in the same time, it set up a control tower platform and make several specific construction companies. This control tower platform mixed profitable projects and unprofitable public projects to borrowing money from bank for passing the loan screening of bank. So in this type can make more non-performing loan than other types.
