Summary: This study examines the impact of digital finance (DF) on carbon intensity (CI) using spatial econometrics based on panel data of 284 prefecture-level cities in China from 2011 to 2020. The results demonstrate an inverted U-shaped relationship between DF and CI. DF has a positive spatial externality on CI, affecting both local CI and surrounding areas. The positive effect is more pronounced under reasonable financial supervision.

Summary: This research explores the factors that shape investor sentiment in the financial market by incorporating information manipulation into the micro-structure. The model suggests that insiders inflate the fundamentals to boost market prices, with manipulation costs acting as a noisy signal or sentiment. The level of manipulation is influenced by market supply elasticity and transparency. The study highlights insider manipulation as a potential source of market sentiment.

Summary: China's practice on promoting interoperability on digital platforms in the field of social media and mobile payment scenarios shows limited convenience for consumers and favors competitive platforms rather than facilitating the entry of small operators. The administrative forces' promotion of interoperability grants a competitive advantage to state-owned enterprises and reduces incentives for existing platforms to innovate and expand. These results validate international concerns about the limited impact of mandatory interoperability in breaking the network blocking effect of internet platforms.

Summary: This paper explains the counter-intuitive practice of online platforms voluntarily referring customers to their direct competitors by developing a game-theoretic model. The study finds that when platforms and sellers are integrated, competitor referral will intensify competition and thus no platform is willing to refer its competitor voluntarily. However, when platforms serve as independent marketplaces for sellers, they may voluntarily refer their competitors to address the issue of double marginalization. The research also shows that if two platforms serve one common seller and the seller does not charge discriminated prices for the same product, referral can also be applied.
