By setting a pivoting foot to the both sides of document and field survey, this research aims to reconstruct the history of a transmigration of the Tai people dispersed globally, and also aims at clarifying their movement of networking, and the transformation of their identity accompanying the networking.

This research aims to reappraise the dynamic transformation in the Early Modern Southeast Asian mountain world through production and trade management of forest products, taking notice of the linkage between local resource and global market. Although it is known that the Northern Indochina mountainshaving supplied the forest product, such as benzoin, aloeswood, and cinnamon which the natural environment produces historically to global market, few studies focused on the reaction of local societies toward global market. Then, we are elucidating linkage between transformation of the societies in the mountains during the period and global market through their involvements in forest products production and trade by analysis of the official documents of Vietnamese dynasties and field data.
