西汉定都长安 ,是由于关中优越的地理位置和良好的经济基础 ;西汉定都长安之后 ,围绕都城的建设和发展以及其他一系列的政治、军事和经济的需要 ,关中地区的经济格局也发生了很大的变化。这种变化主要表现在两个方面 ,一是手工业和商业在经济中的地位大幅度上升 ,经济结构发生了明显的变化 ;二是由于不同地区与都城间相互位置发生转化 ,各区域的经济功能产生差异 ,区域差异性特征日益明显。东汉迁都洛阳之后 ,关中地区的手工业和商业迅速衰落 ,但由于关中的政治中心一直位于西南区 ,所以西汉时期形成的这种经济格局相沿至今 ,没有发生大的变化 The capital of Changan in the Western Han Dynasty was due to the superior geographical location and good economic foundation of Guanzhong.
