后进省区经济发展的外部环境和内在机制分析

本文认为，我国后进省区经济发展的实质，在于选择合理的区际联系形式，在发展过程中建立起与国家及先进省市的动态协调关系。从后进省区的外部环境和内在机制两方面调整经济结构和经济活动的空间结构，才有可能形成动态协调的基本格局。调整外部环境的空间结构，要求实施全国经济宏观布局的类型区开发和局部梯度扩散战略；调整其经济结构的基本手段是重新塑造国内专业化格局。在内在机制方面，空间结构调整应在后进省区建立起增长中心系统；经济结构调整则是扩大经济活动的省区内循环，并建立起具备多适性的产业层次。

AN ANALYSIS ON THE EXTERNAL ENVIRONMENT ANDINTERNAL MECHANISM OF ECONOMIC DEVELOPMENTIN THE LESS DEVELOPEDPROVINCES OF CHINA

: The paper deals with the economic dcvelopment of less developed provinces of China from the 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 comes from suitable external environment endowed by the nation and developed provinces and strong developing capacity boost interior less developed provinces. The basic lneans is to adjust the economic structure and spatial structure. The spatial structure of external environment means to select rational territorial process of national economic derelopment. The countermeasure suggested is the strategy of typologic district 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 specialized production. Trans-provincial division of basic production series of the same industrial sector should be avoided when the division occurs among industrial sectors and so is the gradational division of technology when the division occurs in industrial sector. The spatial adjustment in less developed provinces should establish a growth pole system that 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 at the bottom should be given prominence. The adjustment of economic structure should expand the regional innefr-circulation of economic activities.
