ABSTRACT

Incubators are rated as public policy mechanisms driving innovation in companies. The purpose of this project was to ascertain the level of development of competences for innovation in Technology-Based Enterprise Incubators (TBEI) as perceived by businesspeople in associated companies. With regard to technological innovation, it was decided to use a neo-Schumpeterian approach, and with regard to competences, the Resource-Based View (RBV) theory was used, which evaluates internal attributes that contribute directly to the innovative capacity. Four constructs were taken into consideration for analyzing the development levels of competences for innovation, grounded on the model of François and colleagues (1999 François , J. P. , Goux , D. , Guellec , D. , Kabla , I. , and Temple , P. ( 1999 ). “Décrire lês Compétences pour l'innovation: une Proposition d'enquête.” In: Foray , D. , and Mairesse , J. (Eds.), Innovation et Performance, Approaches Interdisciplinaires , Editions EHESS . [Google Scholar]) and Munier (1999 Munier , F. Taille de ( 1999 ). La Firme et Innovation: Appoches Theóriques et Empiriques Fondées sur le Concept de Compétence , Thèse (Doctorat en Économie)—Estrasburgo: Université Louis Pasteur . [Google Scholar]). Competences for innovation were examined through a questionnaire that tries to identify and assess development levels of competences in TBEI. The findings were analyzed through construct reliability tests: summated scales and cluster analysis. It was noted that the means competences representing the basic resources needed for the development of the company were assessed favorably by the businesspeople, indicating the development of this competence. In terms of technical and relational competences, it was noted that the businesspeople assessed these aspects unfavorably, indicating that these competences are not well developed by the TBEI. It was also ascertained that corporate development levels and operating sectors also influence the assessment of these businesspeople in terms of competences for innovation. This leads to the conclusion that its effectiveness must be assessed as an agent of innovation, with indicators being defined to measure the effectiveness of its role as a mechanism driving technological innovation.  相似文献

This article investigates if investing in local hedge funds improves the risk-return relationship of Brazilian pension funds. Investment in hedge funds by pension funds is growing elsewhere, with an increasing utilization of a multiplicity of hedge funds specialized in specific strategies or niches. We analyzed the performance of a typical pension fund allocation in Brazil as well as alternate allocations that included hedge funds. We used robust estimates of the covariance matrix to mitigate the errors in variables that are problematic in the inputs of the optimization. The results show that hedge funds improve the risk-return relationship of the typical pension fund allocation, contribute to a higher accumulated return at the end of a one-year period, and reduce portfolio rebalancing. Investments in hedge funds ease reaching the typical 6% annual return target with less risk exposure.  相似文献

This study aims to investigate whether foreign direct investment (FDI) growth improved the Brazilian foreign trade in the long run and whether there is a predictable relationship between a firm's FDI strategy and a firm's foreign trade. We applied moderated multiple regressions and generalized linear models to test the effects of FDI on both export and import equations of 11 Brazilian industries from 1996 to 2009. Our data sources include the Ministry of Development, Industry and Foreign Trade Ministry, Central Bank of Brazil, and the Applied Research Institute. Results showed that FDI is correlated with increased exports in the short run, but not in the long run. In the long run, the positive relationship between FDI and exports will only occur for export-oriented industries in which resource-seeking strategies are preponderant. We found a positive relationship between imports and FDI in the short run, particularly in import-oriented industries. A negative relationship between FDI and imports was found in the long run.  相似文献

This paper aims to contribute to the debate concerning whether entrepreneurial posture (consisting of innovativeness, risk taking, proactiveness, competitive aggressiveness, and internal locus of control) is a unidimensional or multidimensional construct. Furthermore, it identifies the profile of Angolan entrepreneurs in terms of their entrepreneurial attitude, and investigates how this profile enhances business performance. The findings suggest that entrepreneurial posture is a multidimensional construct. However, they also suggest that the three entrepreneurial clusters behave differently. Implications for Government and decision-makers, and suggestions for future research are given in the concluding section.  相似文献

This research evaluates cooperation with key suppliers and customers, correlating cooperation to financial performance. Four cooperative behaviors represent cooperation as a multidimensional concept and the research explores the effect of each of these different dimensions of cooperation on performance. Results show that not all cooperative behaviors have similar and positive impacts on performance. Flexibility has no significant effect while shared problem solving has a negative effect. The other two cooperative behaviors, information exchange and restraint in the use of power, have positive impacts on performance. Results also indicate that cooperation with customers affects mostly firm growth while cooperation with suppliers affects firm profitability. Based on a survey of 124 packaging manufacturers, the analysis uses CFA (Confirmatory Factor Analysis) to validate the measurement of constructs and multiple regressions to analyze the relationships between the cooperative behaviors and financial performance.  相似文献

Building on the numerical solution by Ribeiro et al. (2108), this paper proposes a model to assess the impact of volume uncertainty on construction projects' value and on the optimal bidding price. The model's outcome is the threshold amount for the incremental investment that managers have to undertake in order to resolve the uncertainty regarding the volume of work to be performed. Any amount of investment below the threshold will add value to the project and produces a more competitive bid price. A numerical example is presented, and a sensitivity analysis is performed to the model's most relevant components.  相似文献

One of the main research questions in the field of strategic management is why firms obtain different performance levels. This paper answers this question from the strategic groups approach. This paper analyzes the linkage between strategic groups and firm performance offering a multilevel analysis about the relative importance of intergroup and intragroup performance differences based on the use of hierarchical linear models. The results show that intragroup differences explain firm performance better than intergroup differences.  相似文献

Extant research argues that borrowing from financial intermediaries subjects managers to external monitoring. However, given managers' flexibility in choosing the type of debt financing, why would managers submit themselves to external monitoring? Recent theory points to the role of managerial incentive compensation. Specifically, it is argued that managers will borrow from financial intermediaries if their compensation is tied to firm performance. Additionally, it is noted that a more optimal compensation scheme will induce managers to undertake intermediated loans only when the firm is sufficiently profitable. Such a compensation scheme is likely to exist in opaque firm settings where borrowing from financial intermediaries can serve to signal firm profitability. Our study provides corroborative evidence. We find that the choice of syndicated bank loans is positively associated with CEO equity incentives. Second, this syndicated debt-incentive compensation link is influenced by firm profitability, particularly among information problematic firms. Overall, our study points to the role of incentive compensation in the debt placement decision.  相似文献
