Abstract: This study investigates the impact of policy uncertainty in carbon emissions, green energy, and high-tech sectors on China’s financial market. For this purpose, we develop four specific indices—artificial intelligence policy uncertainty (AIPU), carbon emissions policy uncertainty (CEPU), green energy policy uncertainty (GEPU), and high-tech policy uncertainty (HTPU). Using wavelet coherence analysis, we examine the dynamic relationships between these uncertainties and the Chinese stock market from a time–frequency perspective over 2000–2023. Results show that AIPU has the most pronounced long-term impact (32–64 months), CEPU exerts the strongest and most consistent influence in the medium term (12–16 months), GEPU is more prominent in the short term, and HTPU presents a fragmented, less stable pattern.
