    Technological enclaves and industrial districts: An analysis of the regional distribution of innovative activity in Europe

    Get PDF
    This paper explores the spatial distribution of innovative and productive activity across 109 regions of the European Union, thanks to an original databank on regional patents statistics. The main results worth highlighting are as follows. The technological activity in the EU appears to be highly concentrated, although concentration tends to decline over the eighties. This results from the huge differences between southern and northern Europe. As expected, there is a positive association between the regional distribution of innovative activity and labour productivity. Further, contrary to previous evidence on the United States, our data show a significant link between the specialisation in innovation and in production both at the country and at the industry level. This suggests that localised knowledge spillovers and agglomeration economies foster a local economic system towards a specialisation in both production and technology. More surprisingly there appears a negative correlation between technological concentration and aggregate productivity, that is the European regions which enjoy a more homogeneous distribution of their technological capability across different industrial sectors appear to be also characterised by a higher productivity level. This outcome may suggest the presence of positive inter-industry externalities that favour those regions which succeed in covering a broader range of technological activities.

    Harvesting systems for steep terrain in the Italian Alps: state of the art and future prospects

    Get PDF
    Steep slope forest operations in Central Europe and in particular in the Alps are strongly related to the adoption of the cable-based harvesting system, even if innovative ground-based harvesting system, even if innovative ground-based harvesting systems have been proposed in the last years. In this context, the present works aim to acquire a thorough knowledge of yarding technologies used by the logging companies of the central Italian Alps, to evaluate their professionality in steep slope forest operations, and to predict the potential diffusion of innovative steep slope harvesting systems in the area. The results show a large number of logging companies (106) working with cable-based systems and in particular with four different standing skyline yarding technologies. The analysis of professionality in using cable cranes shows big differences between the companies. In particular, it identifies a consistent group of companies with a highly mechanized machinery fleet and high skills and experience in steep slope forest operations. These enterprises evidence a still limited potential diffusion of the innovative ground-based harvesting systems in the area, even if it is theoretically possible according to the GIS analysis of morphology and forest road networ

    Productivity growth in the Old and New Europe: the role of agglomeration externalities

    Get PDF
    The recent history of Europe is characterized by a dual picture showing the Old and New countries in sharp contrast with respect to their industrial specialisation and economic performance. We aim at analyzing the intertwined performance of regions and industries in New and Old European economies by investigating the effects of local agglomeration externalities (mainly specialisation and diversity externalities) on total factor productivity dynamics. We also analyse the potential influence of regional intangible assets such as human and technological capital. The econometric analysis makes use of spatial econometric techniques to take into account the possibility of cross-border externalities.

    Spatial spillovers and innovation activity in European regions

    Get PDF
    This paper explores the spatial distribution of innovative activity and the role of technological spillovers in the process of knowledge creation across 138 regions of 17 countries in Europe (the 15 members of the European Union plus Switzerland and Norway). The analysis is based on an original statistical databank set up by CRENoS on regional patenting at the European Patent Office spanning from 1978 to 1997 and classified by ISIC sectors (3 digit). In a first step, a deep exploratory spatial data analysis of the dissemination of innovative activity in Europe is performed. Some global and local indicators for spatial association are presented, summarising the presence of a dependence process in the distribution of innovative activity for different periods and sectors. Secondly, we attempt to model the behaviour of innovative activity at the regional level on the basis of a knowledge production function. Econometric results points to the relevance of internal factors (R&D expenditure, economic performance, agglomeration economies). Moreover, the production of knowledge by European regions seems to be also affected by spatial spillovers due to innovative activity performed in other regions. Keywords: Innovative activity, Spatial analysis, European regions, Knowledge production function.

    Duplication of modules facilitates the evolution of functional specialization

    The evolution of simulated robots with three different architectures is studied. We compared a non-modular feed forward network, a hardwired modular and a duplication-based modular motor control network. We conclude that both modular architectures outperform the non-modular architecture, both in terms of rate of adaptation as well as the level of adaptation achieved. The main difference between the hardwired and duplication-based modular architectures is that in the latter the modules reached a much higher degree of functional specialization of their motor control units with regard to high level behavioral functions. The hardwired architectures reach the same level of performance, but have a more distributed assignment of functional tasks to the motor control units. We conclude that the mechanism through which functional specialization is achieved is similar to the mechanism proposed for the evolution of duplicated genes. It is found that the duplication of multifunctional modules first leads to a change in the regulation of the module, leading to a differentiation of the functional context in which the module is used. Then the module adapts to the new functional context. After this second step the system is locked into a functionally specialized state. We suggest that functional specialization may be an evolutionary absorption state

    The State of Organic Seed in Europe

    This booklet will present the information collected through research of the LIVESEED project in order to shed light on the actual situation of organic seed use in Europe. In particular, it will focus on the following questions: 1. How does the farmer know what varieties are available as organic seed? How do organic seed databases work in different EU countries and how could they be improved? 2. How much non-organic seed or planting material is used in EU organic farming? How many derogations are granted in different EU Member States and Switzerland? 3. Which are the factors encouraging or discouraging farmers to use organic seed? Which farm and farmer characteristics influence adoption of organic seed? How can organic plant breeding contribute to 100% organic seed use? 4. How has the organic seed market developed in the last years? According to seed suppliers` perspective, what factors hamper the further development of the organic seed sector? To answer these questions, researchers in the LIVESEED project applied integrated research tools and methodologies: a comparative review of the different databases on organic seed in 28 EU countries; an integrated analysis of national derogation reports to measure the current use of nonorganic seed in Europe; a survey among farmers, to understand their perspective on the use of organic seed; and finally a survey among seed suppliers to evaluate trends in the offer of organic seed on the market. A quantitative model was used to estimate the potential demand for organic seed in Europe on the basis of the data collected

    Externalities, knowledge spillovers and the spatial distribution of innovation

    Get PDF
    The empirical literature on economic growth has recently devoted increasing attention to the issue of regional disparities. The first part of this paper is devoted to the analysis of the growth process of 110 European regions using an updated version of the database set up by the Centre for North South Economic Research (CRENoS). Applying various statistical tools, it compares the dynamics of both per capita income and labour productivity. The second part of the paper examines more specifically the economic performance of Sardinia, relative to the European regions, and outlines a general interpretation of the economic growth process of this region

    The role of specialisation and diversity externalities in the agglomeration of innovative activities

    Get PDF
    This paper contributes to the analysis of the process of spatial agglomeration of innovative activities by investigating directly its determinants. Our main purpose is to identify the extent to which the degree of industrial specialisation (Marshall externalities) or diversity (Jacobs externalities) in the region may affect the innovative output in a particular local industry. Moreover, we test if any relevant difference arises with respect to the role of diversity in metropolitan areas and in high-tech sectors. The analysis is carried out thanks to an original databank on innovation and production across Italian local labour systems. According to the estimation results there are clear signs of the two types of externalities working simultaneously: Marshall externalities (or localisation economies), associated to industrial specialisation within the sector and also within the science base cluster; and Jacobs externalities (or urbanisation economies), associated to the degree of diversity of both the local districts and the science base cluster. With respect to the industrial diversity at the local district level, however, it is worth noting that it plays a different role depending on the dimension of the local district (whether it is a metropolitan area or not) and on the type of industry (high Vs low tech sectors)

    Externalities and local economic growth in manufacturing industries

    The growing interest on the economic geography issues has provided new vigour to the research efforts aiming at explaining economic phenomena without neglecting space. In particular several studies have focused on the role of spatially bounded externalities on firms agglomeration processes at the local industry level. This paper has a twofold objective. Firstly, we outline a general eclectic model of local economic growth to provide the theoretical background to guide the econometric analysis. The model includes a general taxonomy of different factors which may explain economic growth in a specific industry and location. Secondly, we assess the role of a large set of potential determinants of the process of local agglomeration of economic activity and we address the issue of spatial association of the local growth processes. We apply our model to the case of Italy making use of a very ample database on socio-economic indicators for 784 Local Labour Systems and 97 manufacturing sectors over the period 1991-96. Our econometric results show that local growth in Italy is not a homogeneous process. On the contrary, it is characterized by significant differences across macro regions with respect to the relevance of the explanatory factors. Among the most important determinants of local industry growth, it is worth mentioning the positive role of the diversity externalities. We also find robust evidence of the negative influence of specialisation externalities on labour dynamics at the local industry level. Moreover, we have assessed the effects of other determinants of local growth like: human capital, social environment and public infrastructures. The analysis of spatial dynamics, carried out for the North-East and Centre-North, shows that at the local industry level there are polarisation phenomena at work and that employment dynamics are self-contained within the boundaries of local labour systems once we have controlled for a large set of local determinants
