    Industrialización no tradicional en municipios rurales españoles
    (Universitat Politècnica de València, 2001) Rama Dellepiane, Ruth; Calatrava de Andrés, Ascensión
    [EN] Using unpublished data from DIRCE, Central Direction of Enterprises from the National Institute of Statistics, this article analyses the evolution of the stocks of companies in 21 processing industries in the second half of the 90s. The aim of the article is testing the hypothesis of an urban/rural shift in industrial location in Spain and in three of its regions: Andalusia, Castille-La Mancha and Catalonia. These data are checked with information provided by field research in rural municipalities of Castille-La Mancha. The study concludes that the «shift» is having place both at the national and the intra-regional levels. Given that its manifestations and rhythms are evident in different regions, one can deduce that general factors must be more important tan local factors to explain this shift. While mature industries are still major activities in rural areas, the empirical evidence shows that the «shift» is more important in basic and high-tech industries tan in traditional ones. We conclude that, paying attention to the problems of non-traditional industries in rural áreas and especially to emergent high-tech activities that have shown –against all prognostics- a special aptitude to develop in rural areas, is an urgent task.

    Análisis bioeconómico del cultivo de dorada en Canarias y en el Mediterráneo
    (Universitat Politècnica de València, 2001) Gasca-Leyva, Eucario; León, Carmelo; Hernández, Juan María; Vergara, José Manuel
    [EN] Aquaculture is an expanding industry, which represents an altemative to the limited fishing resources. This paper develops a bioeconomic model for the production of gilthead seabream, a species with large market potential. The model is based on a biological growth submodel, where fish growth is related to fish weight, ration size, and temperature. Random factors are introduced through the functions for temperatura and market price. A dynamic system methodology is utilised for analysing the temporal evolution of the biological and economic relationships. Since plant localisation is determined by environmental factors, and therefore has an influence on firm retums, the model is utilised for evaluating the impact of two altemative scenarios: the Mediterranean and the Canary Islands. As a main conclusion, it is obtained that competitiveness in the Canaries depends on the production of 750g. extralarge size, which is not profitable in the Mediterranean sea due to large costs. The results also show increasing retums to scale, and the efficient plant capacity for the representative firm.

    Comportamiento de los sectores de la industria alimentaria desde la perspectiva de las tasas de absorción interna
    (Universitat Politècnica de València, 2001) Sala Rios, Mercè
    [EN] The present work, analyses the evolution of nourishment industry in the spanish economy in the period of 1986-1998. The objective is reach conclusions about specialized productivity, demand and exterior interchanges. These conclusions are based on each sector. The nourisment industry is divided into twelve sectors which will be treat. Definitively, it is about to evaluate main changes in diferents sectors of market by an accounting model which considers the equality between resources and employment. The model, will allow us to bring near terms as absorption rate, opening rate, penetration rate and cover rate. These terms are connected and they will be useful supporting our reasons.

    Evolución del mercado y la estructura productiva del sector lácteo español desde la integración en la CEE
    (Universitat Politècnica de València, 2001) Sineiro Garcia, Francisco; Valdês Paços, Bernardo
    [EN] The milk quota system has increased the rate of the process of dissapearance of farms, affecting mainly to smaller size units, while at the same time it was developing a group of medium and big size, as a result of improvements taken in those farms, which are the main responsables for the increase in milk production. The viability of part of these dairy farms is under question because of a quota deficit and of reduced size and lack of sucession. The limitations derived from land availability have forced to an increased use of concentrates which reduces their ability to compete in costs. The moderate increase increase in consumption of dairy products in the spanish market and the reduction of direct sales has allowed the expansion of dairies and a increase in the deficit of external trade. The main changes in dairies have been a process of concentration resulting in the constitution of medium size groups and a increase in the share of foreing enterprises. The Agenda 2000 agreements, the existing round with the WMO and the negotiations to the UE enlargement are going to result in new changes in the milk policy, which will further affect the spanish dairy sector.

    Estimación del valor del regadío a partir del precio de la tierra
    (Universitat Politècnica de València, 2001) Arias, Carlos
    [EN] In this paper, we estimate the value of irrigated land in the province of Leon (Spain) using land prices (irrigated and non irrigated) for two different uses (crop production and pasture) in ten different districts. The value of benefits associated with irrigation can be estimated by comparing the price of an irrigated plot of land with a similar plot of non irrigated land. The logical difficulty of finding these two similar (except for water) plots of land can be overcome using regression analysis where the effect of irrigation on land prices can be estimated after controlling for other differences in the plots of land analyzed. In the present paper, using an econometric model, we estimate the average prices associated with irrigated and non irrigated land. The difference among these average prices is an estimate of the value of irrigation. The results of this paper can be used in the analysis of new irrigation projects.
