  五、活动安排:

  报告一:     

  (1)主题:Banking Market Competition and Corporate Innovation

  (2)主讲人:田琳 经济与管理学院博士后

  (3)交流内容:

  This research is aiming to explore the economic mechanisms through which banking market competition may have any effects on corporate innovation activities. Analysing innovation and bank structure data from China between 2000 and 2013, we show that state-level banking market competition, measured by Panzar-Rosse (1984) H-statistics, increases the number of patents generated by firms and improves innovation efficiencies. The findings strongly support market power hypothesis where with improved banking competition, firms would have better access to bank finance with lower costs to support their innovation activities.In particular, the investigation of the heterogeneity of bank competition impact at the firm-level indicates that the favourable competition effect vary across firm characteristics. Innovative firms, with greater dependence on external finance and being financially constrained, enjoy a greater benefit from increased banking competition. Moreover, complementary to existing literature, this research provide additional evidence showing that the improved bank competition in local markets improves corporate innovation efficiencies, in terms of both R&D input and output at firm level. The finding implies that the increased innovation stemming from the developed banking market would foster creative destruction since output reallocation towards the more successful and efficient firms.

  (4)主讲人简介:

  Dr. Lin Tian holds a Ph.D. degree from the University of Surrey, a Distinction master degree (Msc) in International Financial Management from the University of Surrey, and a Bachelor degree (BA) in Accounting from the University of Wolverhampton in UK. She joined School of Management and Economics of UESTC as a postdoctoral fellow in 2017.

  报告二:

  (1)主题:大规模电商评论中的用户兴趣挖掘:一种动态时间序列观点

  (2)主讲人:李铁 经济与管理学院博士后

  (3)交流内容:

  电子商务网站的评论数据中包含着一种重要的信息——“用户的兴趣”。本研究认为,“兴趣”是用户由于商品购买需求而对某个“商品主题”产生的动态关注过程,“兴趣”的动态性表现为一种随时间的自相关特性,具有长期趋势,并可能呈现周期性的、季节性的波动。本研究基于Spark平台和亚马逊网站的200多万条图书类商品、50多万个用户及600多万条评论数据构建了用户的“兴趣”时间序列,使用ARIMA等模型对兴趣序列进行拟合与预测,并使用DTW对兴趣序列之间的相似性进行了比对,在此基础上构建了用户兴趣网络,并进行了社区发现,最后从推荐系统的角度对用户动态兴趣的挖掘结果进行了评估。

  (4)主讲人简介:

  李铁博士2018年6月毕业于电子科技大学,获管理科学与工程专业博士学位。现为经济与管理学院博士后,主要研究方向为大数据挖掘、征信评估,曾在IEEE Transactions on Systems, Man, and Cybernetics: Systems等期刊发表多篇学术论文,获软件著作权4项。

  报告三:

  (1)主题:Integrated Optimization of Order Selection and Perishable Products Delivery

  (2)主讲人:吴瑶 经济与管理学院博士后

  (3)交流内容:

  In this talk, we mainly discuss the coordination of order selection and perishable products delivery, which are usually dealt with separately by sales department and operations department, respectively. There are two issues to be considered: (1) the necessity of coordinating two processes; (2) how to coordinate the two processes.

  The former problem can be analyzed by the logic theory from the real world practice, and then validated with the comparison of computation results. The latter is the core issue, which should be modeled appropriately, and then solved effectively by a designed algorithm. For a single perishable product delivery problem, to avoid the unnecessary traffic jams in delivery process, time-dependent travelling time is descried as a set of linear functions. Then a mixed integer programming model for integrating order selection and time-dependent vehicle routing problem is developed. According to the model property, a hybrid ant colony algorithm is proposed with associated improving procedures. The efficacy of the proposed model and algorithm is evaluated by four experiments, including a case study, an effectiveness analysis of solving large randomly generated problems and other two sensitivity analysis tests. Accordingly, the problem can be extended to the make-to-order production mode, where production and delivery should be scheduled simultaneously, and coordinating the order selection and production-distribution scheduling is a meaningful and significant problem.

  (4)主讲人简介:

  Yao Wu received the master degree from Southwest Jiaotong University in 2011. Then after a two-year work of teaching assistants, he returned to performing full-time study for PhD degree in the field of logistics and supply chain management. His research interests include variants of vehicle routing problem, integrated optimization of production and delivery, disruption management in production and logistics and uncertain decision making.

  报告四:

  (1)主题:The Mechanism Design and Pattern Innovation of Effective Teaching in Universities——From the perspective of promotion of disciplinary competencies

  (2)主讲人:陈良雨 公共管理学院博士后

  (3)交流内容:

  In this talk, we briefly discuss the background of effective teaching in universities. First, we discuss the connotation of disciplinary competencies. disciplinary competencies is the synthesis of subject knowledge, subject ability, subject thinking mode and subject emotion formed gradually in the course of learning a certain subject.Then, we discuss the obstacles of disciplinary competencies. From the practice of teaching, there are many practical obstacles to effective teaching in universities, which are mainly manifested in the imbalance between teaching results and teaching process, teaching technology and teaching content, imbalance between indoctrination and interaction, and imbalance between knowledge and emotion.Finally, from the perspective of improving disciplinary competencies, we should enhance the effectiveness of teaching through process strengthening, technology embedding, interactive promotion, emotional upgrading and so on.

  (4)主讲人简介:

  Liangyu Chen received the Bachelor degree from Lanzhou University in 2011 and Master degree and Ph.D. degree from the NanKai University, in 2014 and 2017, respectively. He currently works as a Postdoctoral Fellow in the School of Public affairs and Administration of UESTC. Dr. Chen is working in the field of governance of Higher Education. His main research interests include relationship between governments and universities; transformation of higher education; higher education policy; universities governance.

  报告五:

  (1)主题:思想政治观念认同的脑科学认知研究

  (2)主讲人:高杨 经济与管理学院博士后

  (3)交流内容:

  通过认知神经科学的研究成果运用于道德教育之中,设计思想品德认知的功能性磁共振(fMRI)实验,选取与思想品德认知功能相关的脑功能区域进行重点分析,重新审视思想品德认知中的情感与理性之争,着重探讨情绪因素在思想品德认知中的重要作用及其影响思想品德认知的神经机制,以及思想品德认知中情绪与认知的相互作用,以期更好地理解人类自身激发正确思想品德行为的思想品德情感。

  (4)主讲人简介:

  高杨,本科毕业于中国人民解放军军械工程学院获得工学学士学位,2011年和2017年在电子科技大学获得硕士和博士学位。曾经在成都军区装备部服役,在军队期间主要从事“三战”的研究工作,并于2012年荣立三等功1次;2012年被成都军区政治部表彰为“优秀政治工作者”;2016年被西部战区陆军装备部表彰为“优秀基层干部”。高杨博士主要研究方向是网络思想政治教育以及理想观念的脑科学认知。
