What Explains China’s GEM Market? Evidence from the Five Factors
Shengjie Su,Yun Joo An,Moon Sub Choi 아시아유럽미래학회 2020 유라시아연구 Vol.17 No.1
본 연구에서는 Fama-French 5요인 모형과 3요인 모형을 이용하여 중국의 GEM (Growth-Enterprise- Market) 시장에 상장된 주식의 자산가격을 분석한다. GEM 시장은 기술 섹터 중소형 주식 위주로 이루 어진 주가지수이다. 본 연구는 Fama-French 5요인의 설명력을 계산하는 방법론으로 1요인 분석, 다중 요인 분석, 그리고 다중 요인 모형 회귀분석을 사용한다. 본 연구의 결과로는 ‘Robust Minus Weak’ 요 인이 GEM에 상장된 주식의 가격을 5요인 중 가장 잘 설명한다는 것이다. 3요인에 비해 5요인에 새로 추가된 요인인 ‘Robust Minus Weak’ 요인은 또한, ‘Size/Book to Market’ 요인의 설명력을 약화시킨다. ‘Size/Book to Market’ 요인의 약한 설명력은 중소형 주식이 대형 주식보다 size에 대한 민감도가 높아서 이기 때문이라고 결론낸다. We investigate the applicability of the Fama-French five-factor model and three-factor model on China’s Growth Enterprise Market (GEM), which is a small-mid capital equity-based proxy in technology industries. We calculate the explanatory powers of the five factors by contrasting them against single-factor tests, multi-factor tests, and multi-factor model regression. We argue that in GEM, the ‘Robust Minus Weak’ factor best predicts stock price, whereas such profitability factor weakens the potential of ‘Size/Book to Market’ factor. The weakness of size factor is due to the high sensitivity of small-size enterprises on size factor.

In order to research and inquire the development of yoga intervention and health promotion deeply in China and to find out the differences between China and the United States. This research uses Citespace software to analyze the evolution vein, research hotspots, and module knowledge groups of yoga intervention and health promotion research in China and the United States from three aspects: basic information, keywords, and co-citation networks. On this basis, the research theme, formation and development trend of each module knowledge group is analyzed, and the comparative analysis of the research concept, research content and research trend of each module group is carried out. The results suggest that the United States is significantly better than China in terms of total number of publications, trends in publications, volume of journals, and authors" related publications. Plenty of differences do exist in research models, research hotspots, and research continuity between China and the United States. The comparison shows that the United States focuses on the medical value of yoga, while China focuses on the value of yoga exercise. The differences in research concepts between China and the United States have led to differences in research approach and development trends between China and the United States. This study has played a positive role in clarifying the development status of yoga intervention and health promotion in China which could accelerate future research.
