Human capital in the eco-innovative firms: a case study of eco-innovation projects

Purpose - The purpose of this paper is to explain the influence of human capital (HC) on the organizations in terms of eco-innovative entrepreneurship, and the existing relations of these resources with economic and financial resources as well as other capabilities of the firms. A secondary challenge in the research is to define and measure the availability of HC in firms for those eco-innovative processes. Design/methodology/approach - The targeted population for the study was eight eco-innovative companies in Spain. Within each company, a detailed CEO questionnaire was collected to measure HR information, certification or the existence of internal initiatives to promote eco/innovation, and secondary source records to measure economic and financial performance. This data collection strategy eliminated the possibility of percept-percept bias, since the data for each stage of the model were collected from different sources. The database has been analyzed through a qualitative comparative analysis (QCA). Findings - The main conclusion from the QCA analysis indicates that the role of the specialized HC involved in the R&D and innovation activities, the environmental management of firms and the resources (energy) management are relevant factors in the eco-innovative process and they have to be specifically managed for the development of eco-innovations. The qualitative analysis shows that firms that devoted specialized HC to the eco-innovation activities are companies at least ten years old, which have R&D and innovation departments as well as a specific department for the environmental management. They have been certified through some environmental certification standards, have human resources devoted to the product design, promote entrepreneurship for innovation among their own employees and also have higher than the sector average rates of leverage. Research limitations/implications - The main limitation of this paper is linked to the number of analyzed study cases, although all of them are sufficiently representative. Nevertheless, given that the empirical research addressing the interrelated factors of eco-innovation and HC is still not abundant, this study provides an interesting starting point for discussion and the improvement of the qualitative method applied in this paper. Moreover, further research is still needed to fully elucidate how the corporate entrepreneurship is promoted to respond to the eco-innovation strategy of firms, as well as to deeply explore the characteristics of the intellectual capital concerned to the eco-innovation processes. Originality/value - As a novel application, the influence of HC in organizations in terms of eco-innovative entrepreneurship has been analyzed through the measurement of the level of HC specifically devoted to eco-innovation in eight eco-innovative companies. One of the contributions of this study is to define the variables to measure the HC that is available for eco-innovation in an eco-innovative firm. The main conclusions are of interest to practitioners concerning the eco-innovation development in firms.
