Quantifying the vulnerabilities of China’s corporate sector with contingent claims

This paper measures and analyzes the default risk and debt sustainability of China’s non-financial corporate sector both on an aggregate level and within a sector by employing the contingent claims approach (CCA). Our results suggest that the vulnerabilities of Chinese firms are heterogenous in terms of investment source, ownership group, corporate form, industry type, and geographic unit etc. First, foreign capital enterprises have a lower default risk than domestic capital enterprises. Within domestic capital enterprises, state-owned firms have the lowest default risk, whereas private and collective firms are most unsustainable despite that they have the highest returns on assets. Second, state-controlled firms, private stock limited firms, and Chinese foreign cooperative firms are least vulnerable in the state-owned corporate sub-sector, the private corporate sub-sector and the foreign corporate sub-sector, respectively. Third, all industries except the coal industry are sustainable by industry type. Fourth, the vulnerabilities of local state-owned sub-sectors are diverse across China’s administrative regions. Moreover, we provide robustness tests which support our findings. In Sum, our study shed key light on ensuring the soundness of China’s non-financial corporate sector and thereby maintaining the stability and sustainability of the Chinese economy.
