Cost structure and integration in the agro-food sectors: A comparative study in EC countries
使用M. Theil的U指数和投入产出表B矩阵，比较欧共体国家农业食品部门的成本结构和整合程度，发现结构性及价格支持政策部分失效。
Measured by M. Theil's U index, the distance among the columns of Wassily L eontief's technical coefficients show the main differences among the processes of production. Drawn from the input-output table, the B mat rix defines the shares of the each sector output, directly and indire ctly activated by the final demand of different goods. Using the U in dex and the B matrix, the article examines the structure of costs and the degree of integration in EC agro-industrial sectors. It follows that the structural and price support policies are partially inadequa te. Copyright 1987 by Oxford University Press.
