    Abstract

    Cette étude a pour objet d’analyser le degré l’efficacité technique des unités de production informelles et ses déterminants dans le cas de l’agglomération d’Antananarivo à Madagascar en utilisant les bases de données issues d’une série d’enquête de type 1-2-3 sur le secteur informel réalisées en 2001 et 2004. La méthode de la régression par quantile est retenue dans les modèles pour tenir compte des fortes disparités des unités en termes de performances. Le degré d’efficacité des unités de production informelles se situe en moyenne de l’ordre de 33,5% en 2004 et 33,8% en 2001. Les facteurs influant l’efficacité diffèrent aussi selon la branche d’activité. Les contraintes d’offre comme les problèmes liés à l’accès au crédit et au local agissent négativement sur l’efficacité notamment dans les activités de « services ». Dans l’ « industrie » et le « commerce », la relation entre l’efficacité, et le rapport capital/heures travaillées est négative. L’impact de la formation professionnelle suivie par le chef d’unité n’est significativement positif que dans la branche « industrie ». L’« existence de salarié » et l’ « enregistrement » officiel de l’unité de production favorise l’efficacité, notamment dans la branche des «services». Les caractéristiques démographiques du chef de l’unité de production agissent de la même façon, quelle que soit la branche d’activité considérée : effet positif pour l’âge et le sexe masculin. This study has the aim of analyzing the technical efficiency of the informal micro-enterprises and its determinants in the case of the agglomeration of Antananarivo in Madagascar by using the data bases resulting from a series of investigation of the type 1-2-3 on the informal sector carried out in 2001 and 2004. The method of quantile regression is adopted in the models to take account of the strong disparities of the units in terms of performances. The degree of efficiency of the informal micro-enterprises is on average about 33,5% in 2004 and 33,8% in 2001.The factors influencing the efficiency also differ according to the branch. The supply constraints like the problems involved in the access to the credit and the place act negatively on the efficiency in particular in the activities of "services”. In “industry” and the “trade”, the relation between the efficiency and the ratio capital/labour is negative. The impact of the vocational training of the the head of unit is significantly positive only in the branch “industry”. The “existence of salaries” and an official “recording” of the enterprises support the efficiency, in particular in the branch of the “services”. The demographic characteristics of the head of the informal micro-enterprises act in the same way, whatever the branch of activity considered: positive effect for the age and the male sex.(Full text in french)
