The 19th session (the 53rd in total) of the "Engineering Management Forum" series, organized by the School of Economics and Management at Beihang University, was held offline at 16:00 on December 27, 2024, in Room A1028 of the New Main Building. The guest speaker for this session was Professor Jian, an Assistant Professor specializing in Game Theory and Mechanism Design at the Hong Kong University of Science and Technology. The topic of the lecture was "Competition and Cooperation among Transportation Service Providers." The lecture was hosted by Professor Tian Qiong from the School of Economics and Management, with faculty and students from the school attending the session.
Assistant Professor Jian Sisi first introduced the phenomenon of competition and cooperation (often referred to as "coopetition") among transportation service providers (TSPs) through examples. She then introduced a two-stage sequential game model to describe the cooperation-competition problem between TSPs, considering the effects of supply-demand congestion and the asymmetric bargaining power between TSPs. In the first stage, the resource exchange problem was modeled using the Nash bargaining game, while in the second stage, the pricing problem was modeled using a non-cooperative Nash game. Based on this model, Professor Jian explained the impact of the mechanism on social welfare, TSPs, and end users. Finally, she shared her research findings: the resource exchange mechanism can only succeed when the unit price of exchanged resources decreases as the quantity of resources exchanged increases. TSPs tend to leave a certain "buffer zone" between competitors to avoid intense price wars.
Professor Jian's in-depth explanation of the coopetition relationship among transportation service providers provided new research perspectives for addressing the challenges faced by service platforms in the context of digital and intelligent technologies. The faculty and students in attendance engaged in a thorough discussion and exchange with Assistant Professor Jian on the research topic. The seminar concluded successfully in a lively and enthusiastic atmosphere.
Dr. Jian Sisi is an Assistant Professor in the Department of Civil and Environmental Engineering at the Hong Kong University of Science and Technology. She obtained her Ph.D. from the University of New South Wales, Australia. Dr. Jian's research primarily focuses on multi-modal transportation network system modeling and optimization, as well as game theory and mechanism design. She has led projects funded by the Hong Kong Research Grants Council's Outstanding Young Researcher Scheme, the Hong Kong Innovation and Technology Fund, and the National Natural Science Foundation of China’s Youth Fund, among others. Dr. Jian has published over forty papers in SCI/SSCI journals, including leading journals in the transportation field such as Transportation Research Part A, B, C, D, E, AAP, and IEEE T-ITS.
