The paper deals with the economic dcvelopment of less developed provinces of China fromthe angle of economic geography and mesoeconomics. The basic clue is to strive for coordi-nation iri developmental process between the provinces and the country, and between the de-veloped provinces and less developed provinces, as the shortage of close and justice conne-xion is the main problem to be solved for the less, developed provinces. Coordination comesfrom suitable external environment endowed by the nation and developed provinces and strongdeveloping capacity boost interior less developed provinces. The basic lneans is to adjust theeconomic structure and spatial structure.The spatial structure of external environment means to select rational territorial processof national economic derelopment. The countermeasure suggested is the strategy of typologicdistrict that asks to develop the major industries of national economy according to the typo-logic districts and make different types of typologic districts integrated entirely in a province.The economic structurc of external environment means to adjust the pattern of specializedproduction. Trans-provincial division of basic production series of the same industrial sectorshould be avoided when the division occurs among industrial sectors and so is the gradationaldivision of technology when the division occurs in industrial sector.The spatial adjustment in less developed provinces should establish a growth pole systemthat can simultaneously connext conveniently with economic centers of the country and stimu-lat the development of vast areas. The biggest city at the top and the rural market place atthe bottom should be given prominence. The adjustment of economic structure should expandthe regional innefr-circulation of economic activities.
