中文摘要: 本文通过多目标投资组合引入企业社会责任评价指标体系,研究如何量化企业社会责任,并将量化的企业社会责任纳入到投资组合模型中,求解包含企业社会责任的多目标投资组合。 在系统梳理了国内外企业社会责任相关研究的基础上,以KLD企业社会责任评价指标体系为基本框架,提出将企业社会责任(CSR)用经济责任(E)、社会责任(S)、环境责任(C)和公司治理(G)这四个一级指标加以描述,即 ,其中, ( =1,2,3,4)表示权重。每一个一级指标均由若干个二级指标构成,它们分别描述了企业盈利、社会实践、治理、环境等方面的状况。我们采用客观赋权法对各指标赋权。二级指标乘以各自的权重,即为一级指标项的得分;一级指标得分乘以权重,则为企业社会责任的总评分。利用上述公式,我们实证计算了39家上市公司的企业社会责任评分。 在上述研究成果的基础上,我们将企业社会责任引入多目标投资组合管理中,将企业社会责任作为方差和期望收益率之外的又一投资组合目标,构建包含企业社会责任的多目标投资组合。通过最大化期望收益率、最小化方差,以及最大化企业社会责任,将传统的均值-方差二维投资组合选择模型拓展成包括期望收益、方差和企业社会责任感的三维模型,计算拐点投资组合。而通过比较上述两个模型的拐点投资组合,我们发现,包含企业社会责任的多目标投资组合虽然没有均值-方差二元目标的投资组合占优,但其收益率和方差则更为稳定。需要指出的是,相关研究有待于更长时期的数据的检验。  
英文摘要:In this paper, we study corporate social responsibility (CSR) and formulate CSR in a multi-objective portfolio selection model as an extension of traditional Markowitz (1952)’s mean- absolute deviation model. Briefly reviewing the development of CSR, we introduce the KLD rating system as criteria, and propose a quantitative avenue to measure CSR, based on economic (E), social (S), environmental (C) responsibilities, and corporate governance (G) data, that is, , in which, ( =1,2,3,4)is the weight. We set E, S, C and G as primary index, which is composed by some secondary index, describing the corporate profits, social and environmental activities and governance status. We also propose an objective way of calculating the importance of each attribute. Based on Chinese stocks by industries, we formulate 39 stocks’ CSR measurement empirically. Then, through maximizing expected return and the measurement of CSR, minimizing deviation, we incorporate CSR in a multiple objective portfolio selection model as an extension of traditional Markowitz’s portfolio selection model, utilizing Optimizer.xls calculate corner portfolio, which are used to simulate efficient frontiers. In addition, by comparing the approximate efficient frontiers of multiple objective portfolio with CSR and mean-absolute deviation model, we find that although corner portfolios of the latter are dominated that of the former, multiple objective portfolio with CSR gives us more stable corner portfolio, that is, expected return and risk are less variable.
