The existence of a solid service sector and some degree of specialisation in tertiary activities are among a number of territorial diversity of factors which need to be taken into account in relation to the creation of competitive capacities. In addition globalisation has presumably played a significant role in the productive restructuring of economies in which the service sector has had an increasing quantitative and qualitative importance over the years Therefore, an evaluation of the role of services in constructing regional competitive capacities is required. This paper aims at addressing indirectly the meaning of services on improving competitiveness by providing a wide-ranging analysis of regional efficiency of the Mexican service sector and its determinants as well as an overview of its territorial distribution and special isation patterns. We evaluate the patterns of concentration of the third sector and its branches, and specialisation of regions. The efficiency of the service sector in the NAFTA period is analysed further because of the impact of services on regional competitiveness. We employ state leve data to examine technical efficiency's differentials across regions and their determinants. The methodology includes data envelopment analysis to measure technical efficiency which is the dependent variable in a reduced form model that links regional performance with a number of proxies for various types of agglomeration economies such as specialisation, urbanisation and internal economies of scale 展开更多
