Abstract—Currently, the management structures of the business areas and further industrial sites respond to inefficient models, regardless if is the Public or Private Sector who assumes that management. So far an ideal formula has not been found to ensure the provision of basic and advanced services. Nor is there any national solid reference of Public Private Partnership in the business areas management. Although this already exists in the Real Estate Industry, its analysis is far from the purpose of this paper. Here it is analyzed the model of the British BID (Business Improvement Districts), very successful in revitalizing urban centers and small businesses, and their possible application in the business areas of Spain. This work includes, based on critical analysis carried out on three experiences in England, the definition of a new mixed formula called Concerted Management Model, that relies on the currently existing Spanish legislation and that fully reflects the spirit of the BID system. Index Terms—Industrial park, business area, public-private management, BID( Business Improvement District). I. INTRODUCTION It is estimated that there were about 4,800 industrial parks in Spain in 2011, in which a large part of the country’s economic activity is developed; and since they are territorial spaces of great functional diversity, they have some specific necessities which should be considered if they are to maintain or increase their national richness. Considering the lack of public initiative, a few Spanish private associations have set their own goal: the search of management formulas that are efficient in the resolution of the problems of the industrial areas. In this way, we can find some of the works published by The Spanish Coordinator of Industrial Parks (CEPE) [1] [2]. First, the approach was focused on a normative point of view, formulating proposals of legislative reform in urban matter that could be assumed by the Autonomous Communities or, when appropriate, in a specific regulations about business areas [3]. Until now, only the Principality of Asturias has initiated a normative modification in this matter. In the rest of Communities, the initiative did not flourish, either because it was not addressed or, as in Galicia, because it was not promoted in an effective way. In an additional undertaking, the possibility of finding a suitable management formula was analyzed, but such formula also needed Manuscript received June 22, 2013; revised August 19, 2013. Financial support given by the Government of the Principality of Asturias is gratefully acknowledged.

We can say that, if such studies are considered as reference material at a national scale, in practice, the goals have not been reached. In the General Survey on Business Areas in Spain carried out by CEPE in 2012 on a sample of 250 industrial areas of the 17 Spanish Autonomous Communities, it was detected that 74.9% of the business areas did not have any kind of organization that grouped together the various interests of the businesses. The formula used in 20.1% of the cases was that of the Business Association and the other 5% was organized according to mixed systems, among them Conservation Urban Entity which had a frequency of 3%. The data have not been substantially altered through the years; nowadays, according to data of CEPE [1] the businesses that are affected by a lack of maintenance of common spaces are at about 55%. In a qualitative way, the opinions of the business owners shown in the survey highlight are as such:  According to the exclusively public management, the results of the survey establish that it does not reach the minimum levels expected by the businesses regarding to the conservation and provision of basic services.  Although it counts on numerous defenders in the Public Administration, the management approach through Conservation Entities presents many inconveniences and its basis of mature successful models is insufficient. On the other hand, it implies a double burden (imposing and compensation) [4].  The expectations for businesses are focused on the management by private specialists or on mixed methods of management, in the line of numerous experiences applied to the urban centers [5]-[9]. Taking into account the limited success registered by the traditional methods of management of business areas in Spain (totally private or totally public), the object of this work is to determine a new model based on the public-private partnership that will be supported by strong points of an unknown methodology in Spain as in the British Business Improvement Districts. Only some aspects of this system will be movable to the Spanish reality, and always after having submitted them to modifications that allow their adaptation and improvement. In this work, we pretend to establish a general model of public-private management inspired in the BID technology that is applicable to any Spanish business area and industrial park, regardless of their geographic location and therefore of the autonomic rules that can be applied. In this sense, it is to be remembered that the totality of the competences in urban matter and productive space management.
