21评论｜诺贝尔经济学奖：在全球经济低迷中探索内生增长动力

Core Insights - The Nobel Prize in Economic Sciences was awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt for their contributions to understanding innovation-driven economic growth [2][3] Group 1: Theoretical Contributions - Mokyr's research emphasizes the role of knowledge and institutions in long-term growth, particularly in the context of the Industrial Revolution, highlighting the importance of practical knowledge accumulation and dissemination [4][5] - Aghion's core contribution is the "Schumpeterian endogenous growth model," which posits that creative destruction drives productivity growth through quality-enhancing innovations, establishing a relationship between competition and innovation [6][7] - Howitt, in collaboration with Aghion, integrates financial frictions and market structures into the endogenous growth framework, exploring the impact of credit constraints and institutional quality on innovation [7][8] Group 2: Policy Implications - The scholars advocate for a combination of innovation policies that balance incentives and knowledge diffusion, including moderate competition, reasonable patent durations, and R&D tax incentives [9][10] - They emphasize the need for tailored industrial and green policies that consider the specific conditions of advanced and catching-up economies, suggesting differentiated tools for different economic contexts [10][11] - The research highlights the importance of inclusive growth strategies to address income inequality resulting from innovation-driven growth, advocating for education, social security, and retraining programs [11][12] Group 3: Relevance to China - The scholars have engaged with Chinese academic institutions, providing insights on enhancing competition and innovation incentives, and suggesting a "frontier-catcher" policy approach [19][20] - They recommend directionality in technological change and green transformation through carbon pricing and emission standards, particularly in sectors like renewable energy and electric vehicles [21][22] - The emphasis on building a robust knowledge ecosystem and open scientific culture is crucial for China's innovation landscape, advocating for the establishment of engineering communities and industry associations [22]
