    We examine to what extent local firms can reap productivity gains from knowledge spillovers due to the presence of manufacturing affiliates of multinational firms, taking into account that domestic firms' internationalization through import and export activities may also lead to productivity growth. We examine spillovers occurring within sectors as well as those potentially occurring across industries due to client or supply relations of local firms with foreign-owned affiliates in downstream and upstream sectors, respectively. Fixed affects panel analysis on a sample of 4594 local Belgian firms during 2000-2007 reveal significant positive effects of horizontal and backward spillovers on the productivity levels of local firms. Evidence of productivity benefits due to forward linkages from foreign-owned affiliates supplying local firms is only be found for local firms with no export or import activities. Both importing and exporting activities are associated with higher productivity. In general, backward spillovers are weaker for exporting firms, and forward spillovers do not benefit importing firms, suggesting that local spillovers from client/supply relations with foreign multinationals and internationalization can be seen as alternative ways in which internationalization of an economy can enhance productivity performance.

    Decision map for spatial decision making in urban planning

    In this paper, we introduce the concept of decision map and illustrate the way this new concept can be used effectively to support participation in spatial decision making and in urban planning. First, we start by introducing our spatial decision process which is composed of five, non-necessary sequential, phases: problem identification and formulation, analysis, negotiation, concertation, and evaluation and choice. Negotiation and concertation are two main phases in spatial decision making but most available frameworks do not provide tools to support them effectively. The solution proposed here is based on the concept of decision map which is defined as an advanced version of conventional geographic maps which is enriched with preferential information and especially designed to clarify decision making. It looks like a set of homogenous spatial units; each one is characterised with a global, often ordinal, evaluation that represents an aggregation of several partial evaluations relative to different criteria. The decision map is also enriched with different spatial data exploration tools. The procedure of the construction of a decision map contains four main steps: definition of the problem (i.e. generation of criteria maps), generation of an intermediate map, inference of preferential parameters, and generation of a final decision map. The concept of decision map as defined here is a generic tool that may be applied in different domains. This paper focuses on the role of the decision map in supporting participation in spatial decision making and urban planning. Indeed, the decision map is an efficient communication tool in the sense that it permits to the different groups implied in the spatial decision process to ‘think visually’ and to communicate better between each other.ou

    International and domestic technology transfers and productivity growth: Firm level evidence.

    Get PDF
    We examine the drivers of international and domestic technology transfer strategies of firms and the impact of these transfers on firms’ productivity performance in a sample of 440 Flemish innovating firms during 2003-2006. Technology transfers may occur through R&D contracting, purchase of licenses and know how, purchase of specialized machinery, hiring of specialized personnel, and various informal channels. Analysis of the drivers of technology sourcing strategies shows that combined technology sourcing strategies are more likely to be adopted by firms that 1) face resource limitations in their innovative effort 2) have a basic research orientation and conduct more R&D 3) successfully use various technology protection strategies to appropriate the benefits of innovation efforts 4) are engaged in international R&D collaboration. Estimates of a dynamic productivity model show that firms engaging in international knowledge sourcing strategies record substantially and significantly higher productivity growth. The largest impact is found for firms combining foreign transfer strategies with local technology acquisition, suggesting that a diverse external technology strategy combining local technologies as well as know how from abroad is most likely to improve firm performance.Technology transfer; Productivity; Multinational Firms;

    Radiation effects on CMOS image sensors with sub-2”m pinned photodiodes

    Get PDF
    A group of four commercial sensors with pixel pitches below 2ÎŒm has been irradiated with 60Co source at several total ionizing dose levels related to space applications. A phenomenological approach is proposed through behavior analysis of multiple sensors embedding different technological choices (pitch, isolation or buried oxide). A complete characterization including dark current, activation energy and temporal noise analysis allows to discuss about a degradation scheme

    1.4ÎŒm pixel pitch CMOS Image sensors based on hole collection pinned photodiode (HPD) have been irradiated with 60Co source. The HPD sensors exhibit much lower dark current degradation than equivalent commercial sensors using an Electron collection Pinned Photodiode (EPD). This hardness improvement is mainly attributed to carrier accumulation near the interfaces induced by the generated positive charges in dielectrics. The pre-eminence of this image sensor based on hole collection pinned photodiode architectures in ionizing environments is demonstrated

    CMOS image sensor hardness under irradiation is a key parameter for application fields such as space or medical. In this paper, four commercial sensors featuring different technological characteristics (pitch, isolation or buried oxide) have been irradiated with 60Co source. Based on dark current and temporal noise analysis, we develop and propose a phenomenological model to explain pixel performance degradation

    An analysis of national research systems (II): Efficiency in the production of research excellence

    Get PDF
    The main contribution of this project lies in the assessment of the efficiency of national research systems in achieving excellent research performances. The efficiency assessment is not only restricted to the production of research excellence in general, but is disentangled by type of research field, distinguishing between science and technology. This distinction provides a helpful tool for policy makers in assessing the discrepancy of efficiency in both science and technology excellence within and across countries. In our conceptual framework, a national research system’s efficiency can be defined as the extent to which a country is able to transform research assets into excellent research. We conducted efficiency analyses on three main model specifications in which we relate the amount of resource assets (public, private, total R&D expenditure) to the performance on excellent research. In our empirical analysis of efficiency, we report on two methodologies: output/input ratios (partial measures of efficiency) and robust production frontiers (complete and robust measures, order-m and order-alpha method, as developed by Daraio and Simar (2007a). Various conclusions are drawn based on these analyses.JRC.G.3-Econometrics and applied statistic

    Determinants of high-tech entrepreneurship in Europe

    High-tech entrepreneurship is one of the main means by which new knowledge and technologies are converted into economic and social benefits. This report analyses the levels and determinants of high-tech entrepreneurship across European countries. To this end, it uses country-level data on high- and low-tech total early-stage entrepreneurial activity provided by the Global Entrepreneurship Monitor (GEM). Panel data estimations for the period 2007-2014 reveal that EU Member States with better access to finance, less bureaucracy, more consistent policy regimes, favourable entrepreneurship education, and qualitative intellectual property rights that lower patent thicketing strategies exhibit a higher proportion of high-tech firm creation. In addition, greater technological density is associated with a higher rate of high-tech entrepreneurship creation, suggesting beneficial influences of path-dependency and agglomeration effects.JRC.B.6-Digital Econom

    Update on the Composite Indicators of Structural Change towards a More Knowledge-Intensive Economy

    Get PDF
    This report aims at assessing whether the economic structure of Europe is becoming more knowledge-intensive, in comparison with other countries (EU, EFTA and non-European benchmarks US, Japan, China). This entails the measurement of key dimension of structural change with a simple policy tool. The present work builds on and updates the results of the previous Feasibility Study on the development of composite indicators of structural change (Vertesy et al., 2012). It also builds on a previous study by Malerba et al. (2011) that identified indicators measuring changes in the actual sectoral composition of the economy. In this study we construct a composite indicator on structural change at the country level, including indicators on R&D, skills, sectoral specialization, international specialization and internationalization. This composite is a supply-oriented indicator that is largely based on past performance (the outcomes of past efforts that are already measurable in terms of actual value added and employment levels in knowledge-based activities, revealed competitive advantages, supply of skilled human resources, etc.). All these indicators are related to the overall structure of the economy and are slow to change. In order to capture short-term characteristics of structural change related to the dynamics of smaller and younger firms, future research should focus on the development of a longitudinal database collecting indicators on the share of gazelles and the share of high-growth firms in terms of employment and turnover.JRC.G.3-Econometrics and applied statistic
