The objective of the study on the Thai cooperative structure was to proposeappropriate improvement in the Thai cooperative structure which would facilitatefurther development of the Thai cooperatives in general. This study was a qualitativeresearch as to compare between the Thai cooperative movement and the Koreancooperative movement as well as between the Thai cooperative movement and theJapanese cooperative movement. Strength and weakness of the cooperative movement was also analyzed by brainstorming from cooperative experts such asnational excellent cooperators, chairpersons of cooperative federations, boardmembers of the Cooperative League of Thailand and other related people at theCooperative Promotion Department. The group discussion was arranged 2 times.It was found that, in reliance of the cooperation network and supports of variouscooperative and non-cooperative organizations both in the government and privatesectors, the Cooperative League of Thailand could further their legitimate operations todevelop and strengthen the Thai cooperative movement as the leading organization ofthe Thai cooperative movement though there were many restrictions caused by theexisted laws. The study shows major problems which could be concluded namely:1) limited knowledge and understanding of personnel about the cooperative confinedprofessional work even there were many organizations playing the role to promotetraining and education in the cooperative movement. However, the responsibility ofthose training institutes to host trainings were still vague in levels, consequently somecourses were overlapping 2) cooperatives could not link for mutual cooperation andsupport. Their business network, both in the same type and across different types,was weak. The negotiation power was therefore inefficient. 3) There was noorganization directly taking the role in harmonizing the information technologydevelopment system of the cooperative movement and the database of cooperatives’personnel and products was also lacking as there was no linkable in informationtechnology system. 4) The Cooperative League of Thailand had no regional branch forlocal assisting, promoting and supporting cooperatives’ operations. In order to solveproblems of the cooperative movement and to encourage the cooperativedevelopment, four structures were accordingly recommended for the improvementin the cooperative movement namely, 1) the general structure of the cooperativemovement, 2) the structure of the Cooperative League of Thailand, 3) the structure ofthe Office of the Director of the Cooperative League of Thailand, and 4) the structuresof national cooperative federations. It was believed that the network cooperation forsustainable cooperative development would be accomplished if those four mentionedstructures would be strictly followed to implement.
