Abstract: It is very clear that the transport is one of the most important factors for economic development in the Qinghai Tibet Plateau where the poor transport infrastructure has affected local economic development.In Qinghai Tibet Plateau,high transportation cost and long transport distance of the products has not only limited the competitiveness of local enterprises,but also raised market price of the products from other parts of the country.However,in some areas,there are partly development potentials for some industries due to the superior natural resources and relative favorable transport conditions.In this paper,the relationship between transportation cost and economic development is discussed.The development strategies of comparative advantage and unbalanced development should be properly worked out for local economic development.For example,according to the transportation cost,developing local cement industry is benefit for local economy in Tibet.Some key natural resources,such as salt,chromite,and so on,should be developed as key sectors in some areas.

Key words: transportation threshold, comparative advantage, industrial development, key area, subordinate function, guiding function
