建设“丝绸之路经济带”的构想，成为当下中国的国家战略和外交战略。阅读材料，回答下列问题。

材料一：“丝绸之路”始通于西汉张骞“凿空”、在西域设置行政管理机构之时。当时的道路由东而西：自长安经河西走廊通向中亚。经这条路运往西方的商品有蚕丝、丝织品、铁器等，从西方输进中国的商品有良马、葡萄、石榴等。汉代丝绸之路引发了各国互相接触的强烈愿望。

材料二：唐朝丝绸之路畅通，“伊吾之右，波斯以东，职贡不绝，商旅相继”的局面形成后，丝绸大量输往许多国家，外来物品也纷纷涌入。丝绸是唐朝赋税的重要来源，也是政治外交的主要礼物，唐初赠帛与彩缎予突厥，稳定边疆形势。“秦汉以来，唐马最盛”，“绢马贸易”满足了西域各国渴望得到的丝绸，西域骏马也极大地改善了唐朝的军队装备，成为中西交通的重要工具。外来物品如金银带把杯、彩釉玻璃等器皿传入中原，激发了唐朝工匠的仿制兴趣和创新热情，工艺技术的模仿和审美情趣的启示，最终使唐代手工业品的制作风格发生了改变。

    商贸活动带来了文化融合的多元格局。西域音乐、舞蹈、绘画，给传统文化注入清新的气息，以外来乐舞为参照，中国古代“功成作乐”的礼仪制度进行了更新改造。敦煌壁画描绘出只交纳商税、不承担政府义务、定居唐朝境内创业的外国商旅，莫高窟珍藏的大量佛门经文，以及融合西方艺术创造出崭新东方美的造像，将人类共同的美、共同的人性经过潜移默化的整合后以艺术形式再现出来。在不同文明的碰撞过程中，唐朝文化得到了极大的补充和发展，并汇集为开创新时代的动力，最终形成了以唐为核心向四周辐射的文化圈。
