【摘要】 资本资产定价模型(CAPM)是学术界关于现代金融理论研究的焦点。CAPM在中国目前资本市场的有效性需要进一步实证研究和检验。本文以30个行业指数和上证综合指数作为研究对象,利用其在2007年10月15日-2015年9月30日的日交易数据进行时间序列和横截面双回归分析,获得各行业在不同时期的β系数,以此较全面地分析各行业的风险收益情况,并且利用平均收益率和β系数之间的线性关系检验CAPM模型的有效性。更多还原

【Abstract】 Capital asset pricing model(CAPM)is the focus of the academic study of modern finance theory.The effectiveness of CAPM in China’s current capital markets needs to further empirical research and test.In this paper,the indices of 30 industries and the Shanghai Composite Index are chosen as research subjects,and their daily trading data from October 15,2007 to September 30,2015 are used to conduct time series analysis and cross-sectional double regression analysis.Theβcoefficients of different periods in different industries are calculated to analyze the risk and benefit of each industry in a comprehensive way,and to test the validity of CAPM model by using the linear relationship between the average rates of return and theβcoefficients.更多还原
