摘　　要：在发达国家的发展历程中,产业集中度和经济发展水平呈现出U形变动规律。对于中国而言,全国层面的U形特征明显,但U形拐点来得更早;区域内和区域间U形特征不都显著。微观理论模型显示,区域产业集中度水平受经济发展水平、对外开放度和政府干预度等因素影响,但这些因素起促进还是抑制作用与特定时期所在的区间位置有关。计量研究表明,经济发展水平、外商直接投资和政府干预显著促进了全国层面产业集中度的提高,其中,政府干预是U形拐点提早来临和"全国高度集中、区域低专业化"的主因。There exists a U shape betw een sectoral concentration and economic development in developed countries. GINI index of China＇s industry system exists a national U curve and the turning point of the U curve comes earlier w hile there isn＇ t regional and inter- regional U shape. M icroscopic theoretic model indicate that regional sectoral concentration is affected by economic development,opening degree and government intervention,but w hether these factors promote or hold up sectoral concentration depending on regional sectoral concentration level in certain time. M etrical study show s that economic development,foreign direct investment and government intervention obviously promote national sectoral concentration,of w hich government intervention is the primary cause for the early coming of the U curve of national sectoral concentration and ＂high national concentration and low regional specialization＂.
