The Formation of J.B.Clark's economics and American Sociology : A Study of the Correspondence between J.B.Clark and F.H.Giddings.

第一年，j.b.克拉克和f.h.吉丁斯之间未发表的通信几乎全部被抄写了。其分析的第一阶段在第二年开始。它包括克拉克给吉丁斯的265封信和吉丁斯给克拉克的5封信（副本），以及1886年至1930年间写的一份长备忘录。他们大约98%的信件是在1886年至1895年间写的，当时克拉克正在发展他的经济理论，尤其是边际生产率分配理论。这些信件对克拉克边际生产力理论的形成过程，进而对美国边际革命的过程有了新的认识，因此具有重要的价值。吉丁斯在这个过程中扮演了什么角色？他的角色不仅仅是1888年《现代分配过程》一书的合著者。他对克拉克的影响是不小的，至少在以下几个重要的方面：克拉克分配理论的形成，特别是资本和利益理论；静态和动态的区别，以及他的动力学的形成；从基督教社会主义到“进步自由主义”的转变过程中，保守主义思想对克拉克的影响。首次研究结果于1997年6月在日本美国经济思想史学会第三次会议上发表。这本书的题目是《j.b.克拉克和f.h.吉丁斯：他们未发表的通信大纲，1886-1930》。对研究结果进行扩充和修改后的文章《J.B.Clark和F.H.Giddings：他们未发表的通信》发表在《经济评论》（关西大学）1997年10月第47-5期第1-20页。这些信件的文本加上英文的解释性介绍，预定可能在1998年由美国的JAI出版社出版。

In the first year the unpublished correspondence between J.B.Clark and F.H.Giddings was almost completely tanscribed. The first stage of its analysis was begun in the second year.It consists of Clark's 265 letters to Giddings and Gddings' 5 letters (copies) to Clark with a long memorandum written between 1886 and 1930. About 98 per cent of their letters were written between 1886 and 1895 when Clark was developing his economic theory, especially distribution theory of marginal productivity. These letters are of great value, because they shed new light on the formation process of Clark's theory of marginal productivity and then on the process of marginal revolution in the United States. What was Giddings'role in this process? His role was beyond that he became a joint author of the Modern Distributive Process, 1888. His influence on Clark was not small at least in the following important points : the formation of Clark's theory of distribution, especially theories of capital and interest, the distinction between statics and dynamics, and the formation of his dynamics, and the conservative ideological influence on Clark in the changing process from Christian socialism to 'Progressive Liberalism'.The first research results were reported at the third conference of the Japanese Society for the History of American Economic Thought in June 1997. The title was 'J.B.Clark and F.H.Giddings : The Outline of their Unpublished Correspondence, 1886-1930. 'The enlarged and revised version of the research results were published as an article entitled 'J.B.Clark and F.H.Giddings : Their Unpublished Correspondence'in Keizai Ronshu (Economic Review) (Kansai University) , 47-5, pp. 1-20, Decomber, 1997.The texts of the correspondence with an English explanatory introduction are scheduled to be published from JAI Press Inc. in the United States probably in 1998.
