Competitiveness is the most important internal factor to determine a country's export performance. This factor is referenced constantly and it is considered as a necessary condition when it comes to staying in foreign markets, gaining new ones, and increasing the share of exports. This paper is a preliminary study that aims to develop a software tool which is able to characterize the competitiveness of Argentina in the international market for fishery products. We propose to use predicates generated from the knowledge of experts in the study area and evaluate them through Compensatory Fuzzy Logic. The predicates were related to obtain a value that quantifies the competitiveness of Argentina in the various markets in which it provides. The analysis of results verifies the consistency of the computer tool developed. This methodology applied to the fishing industry is an innovative approach to Argentina, not only for the sector in question but also for other industrial sectors that make up the country's productive system 展开更多

This paper has developed a measurement approach that integrates price with the product technical content initiated by Lall et al.(2006),i.e.,dividing HS6-quantile products into high-end,middle-end and low-end levels through the quantile ranking of prices of the same product from different countries or regions in a target market.Our estimation has discovered that due to the lack of product price differentiation,traditional method for the measurement of product technical content overestimated technical content of the low-end segment in the same category of products while underestimated technical content of the high-end segment in the same category of products.Re-calculation based on Rodric's result indicates that specialness of Chinese exports is mainly reflected by high-end and middle-end products.In addition,the competition result of the sophistication of Chinese exports indicates that since the middle of the 1990 s,the sophistication of Chinese exports has remained relatively low compared with the average level of the world and developing countries;from an economic perspective,improvement in the sophistication of Chinese exports primarily derived from middle-end and low-end products;from a category-specific perspective,improvement in the sophistication of Chinese exports primarily derived from low-technology export products. 展开更多
