Dynamic Analysis based upon the Theory of Medium and small-sized Firm and industrial Organization on Elucidation of Changes of the Accumlation Structures and Measures for Promotion of regional located Industry

(1) It is clear that causes of changes of the determinants of market structure, market conduct and market performance with which the producing districts and medium and small-sized firms of regional located industry have confronted are due to background causes showed by dullness of demand in the present extreme depression and complex causes rose from difficulty of grasping of uncertain consumer' s needs, and developing new products and techniques, maldistribution of infonuations, conversions of items and business, etc. . (2) There are several interrelations between dynamic growth processes of medium and small-sized firms and introducing and developing processes of techniques from the viewpoint of changes of the accumlation structures. (3) Diminution causes of the accumulation structures are elucidated by my analysis of the existing statistical data and the results of questionnaire. (4) Dynamic changes of the accumlation structures of techniques is grasped by any fusion between succession of the traditional techniques or its methods and tip techniques, conversions of items and business structures of the producing districts. (5) The accumulation structures in the producing districts are extracted from maintaining or reproducing or developing considerations as well as declining considerations. (6) Policy propositions are presented by countermeasures for dynamic changes in 3 producing districts, survival policy of medium and small-sized firms.
