Our reporter Nanfang
Liu Shulin, a well-known name in the field of mathematical economics research. He has been a visiting professor, researcher and research fellow in Management Science and Engineering at City University of Hong Kong Business w88 casino for many years.Cheng ProfessionalPh.D., Yu2002Comed to w88 casino in 7426_7454 as the director and professor of the Department of Quantitative Economics at the w88 casino of International Economics and w88andDoctoral supervisor;20067751_7780
Over the past few years,Liu ShulinWhile undertaking teaching tasks, the professor has focused on mathematical economics, international bidding and auction theory, game theory, multi-criteria decision-making theory and its application in the fields of economics, w88 and finance, and has published papers in this field30Multiple articles, obtained2001YearNationally OutstandingDoctoral Thesis Award and the Second Prize of the Science and Technology Progress Award of the Ministry of Education, etc. Liu Shulin has chaired several national-level natural science research projects, Ministry of Education Humanities and Social Sciences“Eleventh Five-Year Plan”Planning projects and key course construction teaching projects of the w88 casino’s graduate department.

Expand research and application in quantitative economy
Liu ShulinThe professor's research field is the application of mathematical economics methods. His current research interests focus on the use of game theory, optimization theory, differential equations and probability theory to study bidding and auction theory. The research methods of mathematical economics can be roughly described as (1) Through literature or observation and experience of real economic phenomena, we can draw some economic assumptions and some economic conclusions that are consistent with reality, that is, what is known? What to do? . This step is very important and very difficult. (2) How do you arrive at these economic conclusions, i.e. how do you do it? It is necessary to use mathematical symbols, mathematical functions, mathematical inequalities, mathematical equations, etc. to express or describe these economic assumptions and economic conclusions, that is, (1), the observation and experience of literature or real economic phenomena are expressed as a mathematical proposition or a mathematical model. The remaining work is to use relevant mathematical knowledge to reason; to derive conclusions expressed by mathematical symbols, mathematical functions, mathematical inequalities, mathematical equations, etc.; in the process, some new conclusions may also be drawn.
Another research method in quantitative economics is to start with only some assumptions and roughly know what to do, but not what the conclusion is? At this time, we should try to use these assumptions to conduct mathematical modeling, solve the model, and see if we can draw some conclusions that are consistent with the economic phenomena, or after obtaining the conclusions, try to find economic phenomena that are more consistent. Regardless of the research process or method, assumptions and models may need to be continuously adjusted during the research process until a conclusion is drawn that is consistent with a certain economic phenomenon.
Currently,Liu ShulinThe bidding and auction theory studied by the professor uses decision science and quantitative economics research methods to obtain results. Although most of the results are still at the theoretical level, a small number of research results, such as the results of "multi-attribute decision-making methods and data envelopment analysis", are being applied to their work practice through the on-the-job graduate students he leads, such as the bidding and bid evaluation practice of the State Grid Corporation of China. In addition, this result is also expected to be applied to bidding and bid evaluation practices in the Beijing construction market.
The greatest wish of theoretical researchers is to put research results into practice. But as a scholar,LiuThe professor has a lot of research work to do. When it comes to combining theory with practice, it is easier said than done. There is a lot of difficulty here. Firstly, it takes time to conduct investigations and interviews with actual departments. Secondly, it is very difficult to obtain support from actual departments or obtain real data. Thirdly, whether a cooperative research relationship can be established depends on whether both parties can reach a consensus. Of course, time is never enough for scholars, and the most difficult problem for them is not being able to do anything at all.
Liu ShulinThe professor has established a good cooperative relationship with Zhongdu International Auction Co., Ltd. and the R&D Department of Beijing Construction Market Contracting and Trading Center. The two projects are currently progressing smoothly.LiuThe professor believes that conducting cooperative research with enterprises is the best way to apply theory to practice.

Scientific research must be patient and not afraid of hardships
Liu ShulinProfessor has done many scientific research projects after doing postdoctoral research, working at City University of Hong Kong Business w88 casino and coming to w88 casino, especially in w88 casino5During the year, he presided over as many scientific research projects9Item. So far, he has presided over two National Natural Science Foundation projects. After the two projects were evaluated, one was excellent and the other was good; he also presided over a medium-sized projectCountryPostdoctoral Fund Project; currently hosting a National Natural Science Foundation project and a2005The "New Century Excellent Talents Support Plan" project of the Ministry of Education.
Liu ShulinThe success rate of professors applying for scientific research projects is not low. He believes that it is important to have a correct understanding of the application for scientific research projects. From a general point of view, successful project application is a small contribution to the development of scientific research of the w88 casino and the transformation of the w88 casino into a research university; from a small point of view, the most important thing is whether you have research interests. These two items are the driving force behind the success of applying for a scientific research project. Of course, whether the application can be successful depends on many factors, but the most important factor, which is the factor that you can control, is the preliminary preparation and accumulation, which includes the publication and topic selection of a certain number of high-quality academic papers. Filling out the application form cannot be ignored either. The publication of a certain number of high-quality academic papers requires researchers to have a lot of patience and hard work; in terms of topic selection, the topic may not be a hot research topic in today's academic circles, but you must have your own views and insights in the research.
In research,Liu ShulinThe professor has indeed put in a lot of hard work.40Before the age of 19842_19892|, his solution to the lack of time was to extend working hours, reduce rest time, and not rest during holidays. He basically does it in the early morning every day1Go to sleep.40After 20359_20381|years old, as he grows older, he will occasionally wake up in the early morning1Rest after midnight, but most of the time, he arranges his bedtime to be closer to midnight12Point. Even during the few years he worked in Hong Kong, Liu Shulin was like this. In his busy schedule, he rarely went out of w88 casino. He commuted to and from the w88 casino residence at 2:00 and 1:00 every day; even during the six months of his high-level visit to the United States, he hardly traveled.
Continuously climbing on the road of scientific researchLiuProfessor also expressed his views on undergraduate scientific research project activities. He believes that undergraduate scientific research activities should be diverse. Students can practice the theoretical knowledge they have learned through scientific research activities, and they should be proactive in solving problems encountered in practiceandTeachers discuss and communicate to improve their understanding of knowledge and analytical skills.
