中文摘要：

在研究近40年（1965-2004）全国及三大地带对外贸易总量、对外贸易密度、对外依存度变化及对外贸易区域格局演变的基础上，进一步总结、分析我国七大经济区近40年对外贸易总量、对外贸易密度、对外依存度变化的基本特点及其区域格局演变的基本趋势，并总结对外贸易区域格局形成的基本成因。研究发现，与全国和三大地带的演变趋势相似。①从时间尺度看，近40年，七大经济区的对外贸易发展亦呈长期增长态势，外贸年均增长速度长期高于GDP年均增长速度；②1978年改革开放后国家发展战略、制度、政策的变革加剧推动了时间尺度上七大经济区的对外贸易发展：③但从空间尺度看，东南沿海经济区与其他经济区对外贸易的区域差异格局却没有根本改变：④随着市场经济的发展，其他六大经济区的相对地位反呈较大下降趋势。
