The Journal of Management and Business Research, as the oldest and the most representative academic journal in the field of management in Taiwan, has entered its 36^th year since its first issue. It's been five years since I took over as chief editor of this journal in April, 2014. I have launched several new measures of editing process during my tenure, and many of them have borne fruit. On the aspect of efficiency of the review of papers, I initiated the acceleration of the review of papers since I took office. The time of completing the first review went from an average of seventy-odd days when I just took over in 2014 to an average of 61 days in 2015, to an average of 59 days in 2016, and to an average of 48 days in recent two years (2017 and 2018). The review speed has clearly become much faster.

In order to strengthen the reviewing skill of the reviewers, as well as to enhance the review quality of this journal, the Chinese Management Association (CMA) has held the “Academic Paper Review Workshop” in the annual general meeting every year since 2014. Over the past five years, almost 150 young scholars participated. Substantial benefits of enlarging the reviewer pool and demonstrating the academic impact of this journal can be seen. In 2016, we set up the “Best Reviewer Award” in order to encourage excellent scholars to join the service of academic paper review. The award is based on the review record (such as the quality and speed of reviewing) in the past two years of each reviewer. Each year, two to three best reviewers will be selected and praised after the discussion of the editorial board. Over the past three years, 9 scholars in total had been awarded.

In addition, this journal set up a section named “Editorial Room's Feature Articles” in the end of 2014, inviting influential senior professors from home and abroad to write influential feature articles. Meanwhile, this journal also invites three professors in the related field with high academic prestige to provide their response to those feature articles as complement or extension. Since then, this journal had introduced three articles from chair professor Ming-Che Chen and chair professor Ting-Peng Liang, which are Presidential Address—Becoming Ambicultural: A Personal Quest, and Aspiration for Organizations and The Research-Teaching “Oneness” by chair professor Ming-Che Chen and Developing Management Knowledge Along With Technology Waves: the Drift of a Management Scholar by chair professor Ting-Peng Liang, along with the response articles from nine scholars including chair professor Shih-Chang Hung, chair professor Qiang Gao, chair professor Eric T. G. Wang and chair professor Kwei Tang. These articles had caused huge attention and reaction, further stimulating more new thinking in respect of management.

The Journal of Management and Business Researchhas made much effort in recent years in order to become more internationalized, including establishing English website, attaching English summary and romanized Chinese literature to the published Chinese articles, drawing up the publication ethics statement, etc. This journal was officially included in EBSCO, a database service, in 2015, and is currently striving to expand its international visibility, working ceaselessly and aggressively to apply for other important international databases, such as Scopus.

Looking back at the past five years, apart from gaining the recognition as Tier 1 TSSCI journal by Ministry of Science and Technology for two times, this journal also received the award of No. 1 journal of management in the most influential journal of humanities and social sciences from National Central Library in 2017. Recently, in March, 2019, this journal was given the “Knowledge Communication Award” and the “Knowledge Influence Award” by the National Central Library, which made this journal the only one that received both awards among the TSSCI journals! I'd like to express my appreciation to the two area editors, Prof. Hsueh-Liang Wu and Prof. Robin K. Chou, the advisory board, the editorial board and the administrative editor Ms. Hsiao-Lan Weng for their assistance, as well as Mr. Victor W. Liu, chairman of CMA, and Mr. Yue-Shan Chang, secretary general of CMA, for their huge support that led to the achievement and the smooth running of each project of this journal. I am going to resign as chief editor at the end of this June, and I look forward to much more excellent achievement of this journal under the leadership of the new chief editor.

Four articles are published in this issue. The first article, "Effects of Economic Insecurity on Consumer Ethnocentrism", examines the five experiments conducted on samples from Taiwan and the United States with the concepts of economic insecurity, perceived control, and ethnocentrism from social psychology as research foundation. The research results not only verified academically that consumer perception of macro environment will have an impact on consumer ethnocentrism, but also further clarified the key mental mechanism formed by perceived control as consumer ethnocentrism, providing a viable marketing communication strategy for practitioners.

The second article, "The Information Content of the Length of Annual Shareholder Meetings", mainly explores the determinants of the length of annual shareholder meetings and whether these determinants influence firm performance. This research studied the information of annual shareholders meetings of listed companies in Taiwan over the period 2010–2014 and observed the interaction between outside shareholders and management from a new angle. The research found out that the duration of shareholders meetings has intrinsic information significance that reflects firm performance. The authors suggest that policy makers stipulate related regulations of shareholders meetings in detail and thus expand participation of shareholders.

The third article, "Analyzing Technical Efficiencies of Commercial Banks in Taiwan: An Application of the Bootstrapped DEA Approach", tests the returns to scale and estimates the biased-corrected efficiency scores of the commercial banks in Taiwan, as well as examines the average efficiency difference among different types of commercial banks in Taiwan. In addition to using the data envelopment analysis (DEA), a traditional approach to examine the technical efficiency of commercial banks, as a research methodology, the study also includes undesirable output, which possesses the quality of weak disposability, into the DEA model, and extends the bootstrap method. The results show that the technical efficiency of public banks outperforms that of private banks, while the technical efficiency of financial holding companies is slightly lower than that of non-financial holding companies, but the difference is not salient.

The fourth article, "Private guanxi Between Supervisor and Subordinate: How Private Guanxi Promote Organizational Effects?", starts out from the perspective of subordinates. Through pan-familism, the study explores whether supervisor-subordinate relationships can be developed in Chinese organizations, and when the benefits can be brought to the organizations. This research collects data from full-time employees in a chain food enterprise in the greater China region. The results show that the private relationships between leaders and subordinates enhance subordinates' psychological ownership of the branch and improve subordinates' performance, organizational citizenship behavior-organizational (OCBO) and organizational citizenship behavior-individuals (OCBI). This mediating process will vary with the informal status of an individual in an organization.
