Green innovation investments have rapidly grown since 2000. Green innovation indexes play important roles and are typically constructed by screening and indexing. However, Nobel Laureate Markowitz emphasizes portfolio selection instead of security selection and accentuates that “A good portfolio is more than a long list of good stocks.” Moreover, the screening-indexing strategies ignore that investors can take green innovation as an additional objective and thus gain additional utility. We consequently construct 3-objective portfolio selection for green innovation in addition to variance (...) and expected return. An efficient frontier of portfolio selection then extends to an efficient surface which is a panorama of the optimal variance, expected return, and expected green innovation. Investors thus fully envisage the trade-offs and enjoy the freedom of choosing preferred portfolios on the surface. In contrast, the screening-indexing strategies inflexibly leave investors with only one point. As the originality, we prove in a theorem that there typically exists a curve on the efficient surface so all portfolios on the curve dominate the green innovation index. We test the dominance by component stocks of China Securities Index 300 and obtain affirmative results out of sample. The results still hold in robustness tests. At last, we classify green innovation into categories, further model the categories by general k -objective portfolio selection, and still illustrate the dominance. Consequently, investors can consider and control each category. (shrink)

Opportunistic behaviors are considered ethically and strategically troublesome since they disrupt otherwise mutually beneficial relationships. Previous literature has shown that firms attempt to protect their investments from opportunism by generating a large amount of patented marginal innovations in domains central to their industry. However, this approach may generate some ethical dilemmas by preventing firms and societies from more radical, collaborative, and much-needed environmental progress. We extend the environmental innovation literature using strategic and ethical lenses to analyze the potential of an (...) alternative, divergent way to provide financial opportunities for a focal firm without aiming to prevent innovative opportunities for competitors. Our longitudinal analysis of 6768 environmental patents from 59 large companies worldwide in the electrical components and equipment industry shows that high levels of innovation intensity, environmental scope, bargaining power, and environmental expertise increase the incidence of patented environmental innovations related to domains in which industry competitors are less focused (i.e., technological divergence). We also show a positive relationship between this divergence and market-based firm performance. Our results suggest that pursuing innovative divergence to avoid opportunism may make ethical and market sense and we also identify the organizational factors that can support these efforts.

Whereas extant literature has examined the overall effect of corporate social responsibility (CSR) on innovation, it is argued that CSR is a multidimensional concept encompassing both progressive activities concerning a firm’s engagement in the social domain, as well as rational aspects pertaining to corporate governance practices and the protection of shareholder rights. This study integrates organizational hypocrisy with the knowledge-based view literatures to examine how different forms of CSR engagement affect the rate of new product introductions (NPI). Results suggest that (...) the mechanisms by which progressive and rational CSR are associated to increases in the rate of NPI differ. Specifically, while progressive CSR positively affects the rate of NPI and such effect is deemed stronger for firms that are more vertically integrated, the effect of rational CSR on the rate of NPI is conditional on a firm’s level of absorptive capacity.
