Field Research on Structural Modification of the Automobile Supplier System after the High Appreciation of Yen

我们研究了正在工业化国家大规模发生的世界汽车工业的结构转变。我们特别致力于新的采购政策，开发系统和模块生产系统。我们进一步分析了面对上述汽车制造商转型的供应商的活动。我们进行这些研究时依靠的是出版物。2)走访日本汽车制造商，采访管理人员；我们研究了新的产品开发系统，这是他们为了降低开发成本，缩短交货期而进行的。3)供应商正努力跟上汽车制造商的转型。我们研究了供应商在组件开发方面的承担，特别参考了(1)更好地共享信息的努力，(2)三维CAD/CAM的引入，(3)开发技术的标准化，(4)系统化和模块化的努力。4)根据我们在实地调查中收集的事实，我们展示了自1995年以来供应商进行的30%的成本降低活动的各个方面。5.5)随着一级供应商的成本降低活动，真正的扩张，重组或选择第二和第三供应商也在进行。我们也研究了中小型供应商的这些变化。

1) We examined the structural transformation of the world automobile industry that is taking place in a large scale in the industrialized nations. We devoted ourselves especially to the new purchasing policy, the development system and the module production system. We conducted furthermore an analysis on the activities of suppliers facing the above-mentioned conversion of carmakers. We relied upon publications when we have carried out these researches.2) We visited Japanese automakers and interviewed managers ; we studied the new development system of products, which they have conducted toward reduction of development cost, and shorter lead-time.3) Suppliers are trying to keep up with the carmaker transformation. We studied the undertaking of suppliers on component-development with special reference to (1) efforts for better sharing of information, (2) introduction of 3 dimensional CAD/CAM, (3) standardization of development technology, (4) efforts for systemization and modularization.4) Being based on the facts that we collected in the field survey, we showed the aspects of the cost reduction activities by 30% conducted by suppliers since 1995.5) Along with the cost reduction activities of first tier suppliers, which are truly expanding, reorganization or selection of second and third suppliers is also taking place. We examined these changes in small-and medium sized suppliers as well.
