Abstract
The purpose of this paper is to use China’s World Trade Organization accession as a quasi-natural experiment and examine whether conglomeration affects firmss’ ability to respond to a significant increase in competitive pressure. Conglomerate segments have higher sales growth and higher profitability than singlesegment firms, when they face intensified import competition. Conglomerates’ outperformance is not observed when the markets in which segments operate already have high product market competition. Overall, conglomeration encourages competitiveness, and internal resources are allocated to relatively competitive segments.

Abstract
This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.
