Corporate sustainability strategies in institutional adversity: Antecedent,outcome, and contingency effects

This study examines (i) how top-level managerial institutional ties drive corporate sustainability strategies of emerging market firms operating under conditions of institutional adversity; (ii) the impact of corporate sustainability strategies on market performance; and (iii) the moderating role of financial resource slack on the relationships between corporate sustainability strategies and market performance. The study builds from institutional development logic and the structure–conduct–performance paradigm. Primary data are collected from 300 firms operating in a major sub-Saharan African market. Findings show that top-level managerial institutional linkages with regulatory national governmental officials, local community leaders, and top managers at other firms drive corporate proactive and responsive sustainability strategies, which in turn influence market performance. In addition, the findings reveal that financial resource slack strengthens the path between corporate proactive sustainability strategies and market performance, but not the path between corporate responsive sustainability strategies and market performance. Theoretical and practical implications are discussed.     

海康威视轻资产运营模式转型的财务绩效评价

轻资产运营模式是一种以较低有形资产规模获取较高企业价值的商业模式,近年来受到广泛关注.在这种价值驱动的新型资本战略模式下,企业流动资产尤其是现金类资产较多,固定资产和存货相对较少,企业将更多资金投入到技术、品牌、营销等高附加值环节,通过"轻"资产形态来获取"高"利润回报,并提升财务绩效.本文以实施轻资产运营模式转型战略的海康威视作为案例分析对象,运用纵向案例研究方法分析海康威视轻资产运营模式转型的动因和运营效果,运用财务战略矩阵模型探究轻资产转型对其财务绩效的影响,并针对轻资产运营模式转型过程中存在的问题提出相应对策建议,以期为相关企业进行轻资产运营模式转型提供有益的借鉴.
