报告摘要：
The assumption of a concave production function has long been a cornerstone in economics literature. However, by applying Bayesian Markov Chain Monte Carlo (MCMC) to estimate the structural break, we uncover that since the 1980s, the corporate production function has evolved into a sigmoidal (convex-concave) form, with the convex portion becoming increasingly prominent over time. This structural change, evident across a wide range of countries and industries, quantitatively accounts for the rising share of firms with negative net earnings. Finally, we highlight the welfare implications of this transformation, including the impact of intensified competition and the potential advantages of shifting the tax base from net earnings to gross profits.
