Ainda mais escassos são os trabalhos que buscaram examinar as mudanças na indústria de bens de capital, urna indústria significativamente mais complexa em termos tecnológicos. O presente trabalho tentou contribuir com a historiografia econômica da industrialização brasileira estudando a indústria de bens de capital no estado de São Paulo em aspectos técnicos através de fontes de dados relativamente pouco utilizadas. Os principais resultados encontrados foram que entre 1928 e 1932 o crescimento da indústria de bens de capital é resultado de um aprofundamento do capital, ou seja, um ajuste para um nível mais alto de capital por trabalhador efetivo. Para o período de 1933 a 1937 o fator responsável pelo crescimento nessa indústria foi o progresso técnico ou o trabalho efetivo, dependendo da metodologia adotada / Abstract: The Brazilian industry during the Great Depression has been studied under several angles, but healthy relatively scarce works that are about the eventual changes in the use of produc~ive resources.

Business model reinvention for enabling disruptive innovation

Habtay, Solomon Russom 12 December 2011 (has links)
Over the last two decades, extensive research has been undertaken to understand incumbent firms’ adaptation behavior to disruptive innovation, considering technological change as the most important focus of analysis. Recently, there is an emerging literature that views disruptive innovation as a business model problem in which a technological innovation is deployed. In this literature, disruptive innovation is understood to be primarily a function of conflict between an incumbent’s traditional and an entrant’s new business model. This raises two major questions. First, although the original theory of disruptive innovation evolved from technological studies, this theory persists to explain all types of disruptive innovation over time (Markides, 2006: 19). Furthermore, disruptive innovation has always been studied from an incumbent firm perspective. With the need to shift the research focus from a technology to a business model, we also need a new framework to understand disruptive innovation taking the business model as the unit of analysis taking both the entrant’s and incumbent’s perspectives. Building on business model innovation studies (Govindarajan and Gupta, 2001; Normann, 2001; Hamel, 2000) and the established technology based disruptive innovation theory (Christensen and Raynor, 2003; Christensen, 1997), this study offers a systematic business model framework to comprehend disruptive phenomenon from both an incumbent’s and an entrant’s perspectives. Second, disruptive innovation studies predominantly focus on high-tech industries. Increasingly many low-tech industries are being affected by disruptive non-technological market-driven business model innovations. Considering that disruptive innovation theory is principally iii technology based, a review of the literature suggests that we know little about the differences between high-tech and low-tech market-driven disruptive innovations in terms of their evolutions, competitive and disruptive effects. From the strategic management literature point of view, the contribution of this study becomes even more relevant when the two questions are examined across economic regions. Although there is ample evidence that shows disruptive innovations are not always restricted to developed economies, little is known about how incumbents in developing economies adapt their organizations to disruptive business model innovations. This study takes South Africa as a development economy case-study. The empirical setting of the current study includes four South African industries: the mobile and IT industry (high-tech), banking, insurance and airlines (lowtech) industries. In addressing the two key question of the study, the dissertation presents the empirical analysis at the first-order (firm-level study) and second-order (high-tech vs. low-etch study) levels. The first-order study argues that an innovation creates and grows a niche market through radical product design, different core competencies and/or a different revenue model long before it becomes disruptive innovation. It proposes a framework that attempts to model the evolution of this trajectory from an entrant’s perspective. From the entrant’s perspective, a potentially disruptive business model innovation is a process that evolves over time in successive adaptations to endogenous and exogenous innovation drivers that shape the evolution and path of the new business model. An innovation becomes disruptive only when the new business model fully or partially affects an incumbent’s established business model and market. iv Taking the viewpoint of an incumbent firm, the first-order study further offers a framework that seeks to provide a causality model to comprehend the root cause of disruptive innovation and its impact on the incumbent’s traditional business model. One of the major causes of disruptive innovation is the incumbent’s entrepreneurial dilemma. This means that an incumbent’s success or failure is partly contingent on the senior corporate management’s entrepreneurship readiness that is manifested in terms of taking risk initiative, willingness and ability to take appropriate strategic approaches to enable disruptive innovation. By articulating the causes of disruptive innovation, it suggests four key strategic approaches an incumbent should follow to enable disruptive innovation. While the study finds common patterns for the causes and approaches among incumbents across the four industries at a firm-level, some of the hypotheses of this study could not be proven at an aggregated system level. Disruptive innovation is a relative phenomenon: Some innovations that are disruptive to some firms or industries may not be disruptive to other firms or industries. Therefore, the study further re-examines the aggregated firm-level outcomes by disaggregating the data into dichotomous technology versus marketdriven disruptive innovations. By conducting a second-order analysis at the innovation category level, this study adds considerably to extant innovation literature by establishing that a lowtechnology market-driven disruptive business model innovation entails different business model evolutionary processes, different disruptive effects and different managerial implications compared to high-tech disruptive innovation.

Organisational capabilities for science, technology and innovation policy formulation in developing countries : the case of Nigeria's Federal Ministry of Science and Technology

Daniels, Chux Uzoka January 2016 (has links)
It is widely accepted that public policies have an important role in driving science, technology and innovation (STI) initiatives in order to achieve socio-economic and development objectives. Nevertheless, previous research reveals that developing countries still face difficulties in formulating policies to support and promote STI. A possible reason for this is found in the apparent lack of capabilities for policymaking. Capabilities are "a precondition for effective policy formulation in developing countries" (UNIDO, 2005, p.16). However, our knowledge and understanding of what these capabilities are, remain limited. In this thesis I examine the roles that capabilities play in formulating STI policies, the development of these capabilities and their evolution over the years. I group policy capabilities into organisational capabilities – which refers to policy processes and routines – and individual capabilities – which refers to the skills of individual policymakers (Nelson and Winter, 1982; Dosi et al., 2000; Feldman and Pentland, 2003). In order to address the identified gaps in literature, I use the Nigerian Federal Ministry of Science and Technology (FMST) – which in 2012 completed the formulation of a new national STI policy – as an illustrative case for the investigation of these issues. To achieve the aim of the thesis, I address three research questions: (1) What roles do capabilities play in formulating STI policies at FMST and why? (2) How did policy formulation capabilities originally emerge at FMST and why? (3) How have policy formulation capabilities evolved (i.e. changed over the years, from 1986 to 2012) at FMST and why? To collect data, I interviewed key staff at FMST and stakeholder organisations (who participated in the STI policy formulation exercise), in addition to secondary data from relevant policy documents. The data analysis was based on the “explanation-building” technique (Yin, 2009). The findings reveal the various roles that policy capabilities (processes, routines and skills) play in policy formulation; how and why policy capabilities were developed and their evolution over the years at FMST. The results address the aforementioned gaps. The findings should be useful to policymakers, decision-makers and practitioners involved in STI policymaking, research and capability management.

Fostering technologies for sustainability: Improving Strategic Niche Management as a guide for action using a case study of wind power in Australia

Healey, Gerard Patrick, Gerard.healey@arup.com.au January 2008 (has links)
Society is making increasing efforts to become more sustainable by fostering new technologies such as renewable energy. Often, there are significant challenges to introducing new technologies because existing infrastructure, institutions, social groupings, and behaviours have co-evolved with and consequently support incumbent technologies - a condition known as lock-in. To support efforts to introduce new technologies, researchers have developed conceptual frameworks that aim to increase our understanding of socio-technical change. One promising framework is Strategic Niche Management (SNM); however despite its strength as an ex post analytical tool, SNM has yet to be used to guide experiments with new technologies. This thesis aims to make SNM more usable for those introducing new technologies by responding to four weaknesses identified in existing literature: a weak link between the conceptual framework and action, the vague role of actors, an inadequate appreciation of issues of consensus and limits of influence, and an inadequate appreciation of the challenges that actors may face. This is achieved by identifying promising insights and testing them on a case study of wind power in Australia. The literature review identifies dynamics that have been linked to positive feedbacks in the development of new technologies and socio-technical change. These are: stimulating demand, increasing use, learning and articulation, increasing functionality, decreasing costs, decreasing uncertainty, embedding and alignment, increasing legitimacy, attracting actors, and strengthening expectations and visions. These dynamics can be used to provide a better link between theory and action. The review also identifies particular actor roles - such as niche manager, macro actor, prime mover, and dedicated network builder - and actions that actors in these roles may take. These roles and actions are linked to the dynamics. Also reviewed are issues related to consensus and limits of influence; a particularly useful concept in this regard is resource interdependency. Finally, the review identifies challenges to encouraging the dynamics aimed at helping actors to anticipate problems in the introduction of new technologies. T he relevance of this approach and applicability of these insights are tested with a case study of wind power in Australia. The case study explains changes related to grid-connected wind power in Australia between about 1997 and 2007. There was significant socio-technical change: for example, installed grid-connected wind farm capacity grew from about 1 MW to almost 900 MW, an industry and industry association formed, there were unprecedented changes in energy policy, new high-level actor groups formed to oversee the grid-integration of wind power, Governments amended planning schemes, and public opinion was increasingly articulated. The dynamics identified in the literature review were all relevant to wind power. The study provides examples of the actors that can encourage these dynamics and how they might do so. Most challenges identified in the literature review were relevant to wind power and possible strategies for managing them were identified. Also revealed were challenges in transitional strategies, legitimacy of the technology and consensus. These findings are discussed in detail. These findings are intended to help actors foster technologies for sustainability.
