First, because there have been problems with its implementation direction and capital chain problems in the past few years.

Second, the current PPP suspension areas are limited to Xinjiang (for fear of being harmed if I write the answer) and Inner Mongolia. There is no news of large-scale suspensions in other places. The reasons for the suspension of PPP projects can be roughly divided into the following three categories: (1) Government reasons. Typical examples include a certain place in the northwest and Inner Mongolia, where the government's financial payment capacity is weak. With the support of the state (including the central government and various central enterprises), various PPP projects have been launched one after another. At the juncture of the central economic work focus adjustment, various types of PPP projects have come to an emergency stop. I heard that some projects also require the withdrawal of government funding. All kinds of social capital can only be knocked down and swallowed with blood (2) Reasons for construction companies. When PPP projects were first implemented, some projects had already signed construction contracts in the early stage. Later, due to policy changes, they had to adopt the PPP model. In order to gain market share, some construction units advanced funds before the project completed the storage process. , As a result of the preliminary construction, some PPP projects failed to be put into storage in the end, and the source of income was doubtful. In this case, construction had to be stopped. It is said that a construction unit of a central enterprise has suspended more than 40 billion projects due to this reason. (3) The source of funds cannot be confirmed. It is similar to the above situation, but the difference is that the project has gone through the normal approval process and has been put into the database. However, due to reasons such as Document No. 92 and Document No. 23, the project capital cannot be implemented and subsequent debt financing cannot be negotiated. Construction units of various central-owned enterprises are facing various consolidation pressures and can only temporarily suspend construction. The date for the start of construction is not yet known.

Third, according to data released by Dayue Consulting in March 2018, the total number of shutdowns of PPP projects that have been started in 2018 is approximately 90 billion. project. Theoretically, shutdown means breach of contract, waste of previous investment, and ineffective costs. In other words, the amount of projects that were previously built in vain and may need to be demolished is 90 billion. Who will bear this loss? The construction unit that provides advance funds for construction? A bank that lends money? government? But judging from the current situation, whoever is at the stall is the unlucky one. The dispute is not big. At the same time, 90 billion is not a large amount compared to the amount of PPP projects in recent years. There is no need to be overly pessimistic. The total investment in PPP projects in 2017 was about 2.8 trillion. For this, 90 billion is really a drop in the bucket. A quote from Mr. Jin Yongxiang of Dayue Consulting is "The development of PPP in the past 3-5 years has saved a large number of central enterprises." Its size and influence are evident. Therefore, for the PPP project, the suspension of work of 90 billion can only be said to be the failure of the PPP project, not to mention a halt. At the same time, the failure of PPP only proves that there is a problem with the direction of its implementation in the past few years, rather than a problem with itself. The country's demand for PPP is still there, and the future development of PPP still has broad prospects.
