高等经济研究院杨婉彧副教授的论文在国际权威学术期刊在线发表
2026年08月28日
近日，东北财经大学高等经济研究院杨婉彧副教授与清华大学经济管理学院刘晨源助理教授、陆毅教授合作的论文“Excessive Pharmaceutical Marketing Expenditure: Policy Remedies from China”，被经济学领域权威期刊The Review of Economics and Statistics（学校T1类期刊）接收并正式在线发表。
该研究关注发展中国家药品价格居高不下问题，指出制药企业在销售和营销环节支出过度是重要原因之一。论文利用中国“4+7”国家组织药品集中采购和使用试点，采用双重差分与三重差分方法，考察带有基础采购量的集中化药品采购对营销投入和药品价格的影响。研究发现，中标企业无需承担高昂营销成本即可直接获得较大市场份额；集中带量采购显著降低了销售成本和药品价格，中标企业的营销相关劳动力需求也明显下降。
The Review of Economics and Statistics 是经济学领域，尤其在应用经济学领域具有重要影响力的国际权威期刊。这项研究是高等经济研究院教师以东北财经大学为署名单位发表的第20篇学校T级别研究成果，也是杨婉彧本人发表的第4篇T级别研究成果，此前研究成果发表在 Journal of Development Economics、Journal of Public Economics、《经济研究》等国内外权威期刊。
高等经济研究院持续深化人才管理与科研组织模式改革，着力建设具有国际视野和竞争力的高水平人才团队，深耕基础理论创新，不断推进理论突破与学术攻关。未来，研究院将继续拓宽国际化视野，产出更多扎根中国大地、引领学术前沿的高质量研究成果，助力学校构建中国经济学自主知识体系，高质量推进“双一流”建设。
Associate Professor Wanyu Yang's Papers Accepted for Publication in The Review of Economics and Statistics
August 28, 2026
Wanyu Yang, Associate Professor at the Institute for Advanced Economic Research (IAER) of Dongbei University of Finance and Economics (DUFE), had her paper accepted for publication in The Review of Economics and Statistics ( DUFE Tier-T1)recently. Entitled "Excessive Pharmaceutical Marketing Expenditure: Policy Remedies from China", the paper was co-authored with Chenyuan Liu, Assistant Professor of School of Economics and Management at Tsinghua University and Yi Lu, Professor of School of Economics and Management at Tsinghua University.
Developing countries face high pharmaceutical prices despite the presence of multiple generic producers. One key reason is excessive spending on sales and marketing by drug firms. This paper examines how centralized drug procurement can curb such marketing efforts and reduce prices, using a policy experiment in China where certain generics are procured through centralized auctions in pilot cities. Winning firms gain large market shares directly without incurring high marketing costs. The authors find that the centralized auction significantly reduces both sales costs and prices, with winning firms experiencing notable decreases in marketing-related labor demand.
The Review of Economics and Statistics is an internationally renowned journal in economics, particularly influential in applied economics. The paper is the 20th DUFE Tier-T research output published with DUFE as the affiliation and the 4th T-rated publication by Wanyu Yang. Her earlier work has appeared in top domestic and international journals, including Journal of Development Economics, Journal of Public Economics, and Economic Research Journal (Jingji Yanjiu).
IAER keeps reforming talent and research management to build competitive, globally minded teams and advance fundamental theoretical breakthroughs. Going forward, it will produce more high-quality, frontier research, helping the university develop an independent body of knowledge in Chinese economics and drive its "Double First-Class" initiative.
