Professor Lange, a respected academic with a doctorate in economics and a background in public economics, shared his expertise on "Public Good Provision in the Marketplace." His lecture navigated the market supply of public goods through two lenses: profit-driven and intrinsic motivation-driven approaches. He discussed the profitability of private and charitable organizations in the market and the role of corporate social responsibility in line with profit generation. Lange also highlighted how intrinsic motivation among companies can influence market equilibrium and product quality, emphasizing the importance of external interventions like taxes and standards.

Associate Professor Zhang Junjie from Duke University and Associate Professor Li Zhi from Xiamen University provided insightful commentary on Professor Lange's research. They recognized the significant policy implications of Lange's work, especially regarding corporate social responsibility, and suggested further areas of exploration, including the impact of taxation and subsidies on diverse enterprises and the potential for empirical estimation of consumer altruism.

Professor Lange engaged in a lively discussion with the reviewers, addressing their points and sharing his perspectives on future research directions.

This lecture series continues to provide a valuable platform for sharing the latest research, peer reviews, and multi-dimensional interactions, fostering a learning environment for all attendees and contributing to the field of environmental economics.
