Land development is a type of traditional business. In the past, investors found it difficult to raise enough funds to construct joint development (JD) buildings. Even though a financial assistance mechanism was put in place, in which the government issued certification for acquiring financial support, the risk was still undertaken by the banks and investors. For many projects no bank was willing to cooperate, even the former city government-owned Taipei Bank, and often the government was asked to give a higher level of guarantee, causing serious delays in developments that had fueled great optimism. With that in mind, DORTS referred to related regulations and drew up three corresponding measures: 1. The Taipei MRT Joint Development Financial Assistance Contract, 2. Trust Contract, and 3. The Particular Articles for Taipei MRT Joint Development Investment Contract.
