Dynamic feature inspection.

In the continuous development of the Chinese economy, the desire for common prosperity among the people has become increasingly strong. However, the complex domestic and international situations, along with the economic uncertainties post-pandemic, have introduced significant uncertainties into government economic policies. In the long term, this uncertainty has a profound impact on intra-enterprise common prosperity, affecting society at large. This paper focuses on non-financial listed companies on the Shanghai and Shenzhen stock exchanges from 2011 to 2020, examining the negative effects of economic policy uncertainty on intra-enterprise common prosperity. The results indicate that economic policy uncertainty has a significant adverse impact on intra-enterprise common prosperity, and this impact is more pronounced in state-owned enterprises, those in the growth life cycle, and companies with poor innovation capabilities and limited external support. Companies enhancing social responsibility and overall factor productivity can help mitigate these negative effects. Furthermore, in dynamic features, as the level of intra-enterprise common prosperity increases, the negative impact of economic policy uncertainty gradually diminishes, while the positive effects of overall factor productivity and corporate social responsibility on enterprises become more evident.
