The purpose of this paper is to investigate the effect of the size and the roles of the board of directors (BD) on two types of innovation namely exploitative and exploratory innovations. These relationships have been little explored in the literature, particularly in developing economies. Using a quantitative approach, an empirical study was conducted on a sample of 51 Tunisian listed companies. It revealed that exploratory innovation is promoted by BDs service role. The results also highlight that exploitative innovation is positively related to the BD's strategy role but negatively associated with BD's control role. The findings do not show a significant effect of BD's size on the two types of innovation. This research provides insights to companies looking to improve their corporate governance practices and develop a sustainable competitive advantage based on innovation.

Technology business incubators (TBIs) can be used strategically as mechanisms for innovation and economic development processes in countries, states, municipalities, regions and companies. The study of their management model in terms of organisational efficiency and value creation is important. In this context, the general aim of this study was to evaluate the business models of incubators of technology-based Brazilian and Portuguese companies. With this specific aim, the study sought to: 1) map the resources that affect costs and/or generate revenue; 2) study the nature of partnerships; 3) analyse value propositions; 4) propose a business model for the sustainability of TBIs. The methodology employed was qualitative in nature and the multiple case study method was used at ten TBIs, six of which were Brazilian and four Portuguese. The result was the proposal of a business model for TBIs that includes good incubation practices for companies and helps incubators to achieve sustainability through organisational efficiency and value creation.

This paper is framed within the stream of research that investigates the factors that explain corporate social responsibility and analyses the role played by the immediate area in which a company operates. Its purpose is to examine the impact of science and technology parks on the social responsibility of companies physically located in territorial agglomerations. Using reasoning derived from institutional theory, the study examines the effects of the sense of belonging to a park, the involvement of institutions with links to a park, and the know-how that exists within a park. An analysis of a sample of 239 companies in high tech sectors in Spanish science and technology parks showed that all three aspects have a significant positive influence on the implementation of corporate social responsibility, although know-how was proved to be of secondary importance compared to a sense of belonging and the role played by institutions interrelating with parks.

Business organisations are facing increasing pressure over their role in society. Social innovation is a relatively new concept used to define efforts to develop novel and innovative solutions to social challenges. The aim of this study is to conceptualise a novel form of social innovation, namely, 'corporate social innovation', by focusing on social innovation efforts initiated by private sector organisations. This study also aims to provide insight into: 1) the definition of corporate social innovation; 2) the key dimensions underlying the social innovation capability of business organisations. Data were collected through semi-structured interviews with 20 experts who play an active role in various social innovation projects in their respective organisations and/or adopt social innovation as an academic field of interest. The interview results extend our conceptual understanding of the corporate social innovation phenomenon by providing a comprehensive definition of the concept and describing a six-factor model of corporate social innovation capability.

Crowdfunding is the process of collecting money from a large audience to launch an entrepreneurial project. It is mostly based on the use of internet to gather financial resources and leverage the 'wisdom of crowds' to pre-validate the potential of a business idea. In particular, equity crowdfunding allows broad groups of investors to fund new companies in return for ownership of a piece of the business. It is thus an interesting option for supporting the launch of innovative companies, although its adoption is still limited by a number of complexities and an incomplete awareness of potential benefits. In such vein, this paper delineates the status of equity crowdfunding in Italy and presents the analysis of three successful equity crowdfunding campaigns, with the purpose to collect a set of lessons learned and provide useful insights for entrepreneurs and investors as well.

The entrepreneurship ecosystem concept has been examined by various scholars resulting in different definitions and the development of various frameworks. High-tech entrepreneurial ecosystems are special types that are closely linked to innovative, high growth firms. We argue that the logic of interpretation of high-tech entrepreneurial ecosystems is quite different from that of national entrepreneurial ecosystems. The latter are guided by national policies and follow mainly a top down approach. This paper posits that the emergence and development of high-tech entrepreneurial ecosystems follow mainly a bottom up approach. For this reason, we have used a complex adaptive systems framework to interpret high-tech entrepreneurial ecosystems. In addition, we have also examined the network effects in these ecosystems. Reflecting on these effects, we have highlighted the additional roles of agents such as universities and local governments in contributing to the success of high-tech ecosystems. Finally, we have developed propositions that could be transformed into testable hypothesis and suggested further research.

The purpose of the study is to advance research on open business models as activity systems (Zott and Amit, 2010) in collaborative networks. We utilise Bradley's (1995) theory of exchange behaviour to discuss how new joint activities can be explored and how existing activities can be redesigned to strengthen collaboration between companies. To enable this discussion, we delve into the sensemaking literature and theory from loosely coupled systems. Our discussion leads to the development of the balanced activity system (BAS) model. The paper's key contribution is the prescriptive BAS model, which can be used strategically in collaborative networks to redesign or create new joint activities.

This paper contributes to an integrated entrepreneurship perspective in the cross-section of research on networks, innovation and internationalisation. The study promotes a conceptualisation based on international competitiveness literature in order to further such an integrated entrepreneurship perspective. By focusing on potential international network competitiveness, delineated as network-based sources of international competitiveness, the sustainability of international entrepreneurial firms is emphasised. The paper specifically draws attention to the relationship between network-based sources of international competitiveness and international technology development. Three hypotheses are developed and tested on 142 technology-based internationalising SMEs by means of linear structural relations (LISREL). The results indicate that there are direct- and indirect positive effects between network-based sources of international competitiveness and international technology development.

This paper discusses the opportunities and barriers for the transfer of employees' ideas to implementation of new solutions in employee-driven innovation. The theoretical approach is the existing research not only on innovation transfer but also on the transfer of learning, knowledge and technology. Based on the results from an action research project aimed at training and involving shop-floor employees in employee-driven innovation, the paper identifies five factors that have been crucial to the process of transfer from employees' ideas to new solutions in production. The paper discusses five factors for transfer compared with existing literature and knowledge on employee-driven innovation.

Innovation is typically attributed to certain groups of employees such as functional specialists, professionals, and R&D experts. The innovative potential of lower-level employees is often overlooked. With this study, we contribute to innovation research by analysing the innovative behaviour of ordinary employees compared to other kinds of employees from whom highly innovative behaviours are expected. We develop and test an integrative model of employee driven innovation consisting of different intra-organisational drivers and simultaneously control for personal characteristics. Our results show that the most important factor for influencing innovative behaviour is an appropriate job design that includes autonomy and innovativeness as job requirements. In addition, the personal factors of openness to new experiences and role breadth self-efficacy seem to be essential. Moreover, we found that the degree of innovative behaviour of ordinary employees is not significantly different from other groups of employees who are expected to focus on innovation activities.
