38.(2010安徽卷)(28分)2010年世博会在上海举行。某校高二(1)班同学以“走进世博，聚焦安徽”为主题开展探究活动。同学们通过查阅、上网等途径收集资料，组织课堂讨论，发表看法：
甲同学：上海世博会是文化世博。中国馆的建筑设计凸显汉字、京剧、中国红和水墨画等中国元素，整体布局体现了中华文化悠久的 “和谐”思想;国家馆馆内用高科技手段向观众展示古代四大发明、《清明上河图》等中华上下五千年文明的精华；安徽馆以徽派建筑标志性元素“马头墙、小青瓦”为外墙装饰，馆内通过徽剧、黄梅戏，凤阳花鼓等民间艺术的展示，让观众领略新安文化、皖江文化和淮河文化的质感。
乙同学：上海世博会是低碳世博。以低能耗、低污染、低排放为基本特征的“低碳”理念贯穿于上海世博会方方面面。如世博会的照明全面采用半导体照明(LED)，既不减少亮度又节省能源百分之九十；安徽馆的建筑和装饰大量采用了节能环保产品；安徽将利用世博会推介发展低碳经济的招商项目，承接国际国内产业转移，努力实现跨越式发展。

(2)请你结合乙同学的发言，运用经济生活知识说说发展低碳经济对实现我国经济又好又快发展的积极影响。(8分)
