Clustering Analysis of Risk Divergence of China Government’s Debts

Abstract

It is a difficult time for the world’s economics while the impact of COVID-19 is undergoing. A possible worldwide sovereign debt crisis could emerge, in short term, for supply chains blockage due to its slowing-down in many countries. China, having the second largest economy in the world, is crucial for the stability and sustainability of the economic recovery. China endures a long-term growth since 2000; nevertheless, a large amount of that growth is contributed by the government debt, which was spent on infrastructures. The accumulation of debts is a potential risk to the future growth of China. This research evaluates the central government and local government debts with a series of indicators. The weights of indicators are determined by objective methods of the CRITIC approach. Results confirm that the central government debt of China is on the edge of risk, while the risk of local governments debt is already in a concerning danger. The local government risk is 50% higher than the central government’s risk. Moreover, the K-means clustering algorithm performed on data, collected from various provinces, suggests that the local government debts of China follow a pattern of geographical distribution; that is, the closer to the coast, the lesser the risk, which is in accordance with the pattern of labor flowing. Labors are attracted by job opportunities which lie in the well-developed regions of China. This is confirmed by the crosscheck with the wage growth data. This indicates that the less developed areas of China rely more heavily on debt-investment stimulation that could be of a potential stagnation because the yield of investment follows diminishing marginal returns and the relative lacking labor weakens the potential economic growth.

An Unstoppable and Navigating Journey Towards Development Reform in Complex Financial-Economic Systems: An Interval Analysis of Government Expenses (Past, Present, Future)

“…In terms of the complexity of government spending (Bruce, 1995), it is emphasized that complex financial and economic systems are constructively used to achieve certain spending languages within the complex systems of the country. To elaborate reforms towards economic development in complex financial systems have contributed Ouyang and Lu (2021) which emphasizes that egovernment of complex financial and economic systems has become one of the key points of the government building, but that the degree of success of e-government projects in variables (WS, GS, EU, ST, CE, and TE) both in developed countries and in developing countries it is not high. To look at general government spending on variables (WS, GS, EU, ST, CE, and TE) contributed Sun (2021), where it is emphasized that the Gaussian probability-based semantic analysis model can provide robust, extraordinary detection of anomalies in a fully automated data-driven solution in complex financial systems for government spending.…”

“…As of the end of 2013, the scale of implicit local gove ment debt was 1.75 times that of public debt. The rapidly growing local debt has attrac attention from the academic community [21][22][23]. The rapid growth of local government debt has driven the construction of local pub infrastructure and driven investment by enterprises.…”
