This paper investigates how the Global Supply Chain Pressure Index (GSCPI) affects long-term stock–bond correlations in China, employing mixed-frequency data from April 2005 to June 2025 in a DCC-MIDAS-X framework. Results show that higher GSCPI significantly reduces long-term stock–bond correlations, thereby enhancing the hedging property of bonds. This effect is both state-dependent and asymmetric, remaining significant in low-volatility regimes and following negative shocks, while becoming largely muted during high-volatility periods or after positive shocks. However, the impact of GSCPI weakens substantially after China’s 2014 financial liberalization, as global financial factors increasingly drive cross-asset dynamics. Moreover, GSCPI provides incremental information that enhances portfolio diversification and hedging performance.

Recent studies highlight the resurgence of state capitalism, with the state increasingly acting as equity investors in private firms. Why do state--business equity ties, including partial and indirect state ownership in private firms, proliferate in weakly institutionalized contexts like China? While conventional wisdom emphasizes state-driven explanations based on static evidence, I argue that regulatory risk reshapes business preferences, prompting firms to seek state investors and expanding state--business equity ties. These ties facilitate information exchange and signal political endorsement under regulatory scrutiny. Focusing on China's crackdown on the Internet and IT sectors, difference-in-differences analyses of all investments from 2016 to 2022 reveal a rise in state--business equity ties post-crackdown. In-depth interviews with investors along with quantitative analysis, demonstrate that shifts in business preferences drive this change. This study shows the resurgence of state capitalism is driven not only by the state but also by businesses in response to regulatory risks.
