同类题3

阅读材料,回答问题。

2015年10月,***第十八届五中全会《中共中央关于制定国民经济和社会发展第十三个五年规划的建议》,提出了创新、协调、绿色、开放、共享“五大发展理念”。

【创新发展】材料一:创新发展是“十三五”时期经济结构实现战略性调整的关键驱动因素,是实现“五位一体”总体布局下全面发展的根本支撑和关键动力。但要提高人民的创造性,必须从改革基础教育着手,学校的教育要从“知识游戏”转变为“思想游戏”。

【协调发展】材料二:坚持协调发展,重点促进城乡区域协调发展,促进经济社会协调发展。中国是个大国,地区发展不均衡问题长期存在,中国一直在不同阶段采取不同策略着力解决发展不均衡问题。

【开放发展】材料三:近几年来,特别是金融危机后,欧美等发达国家掀起了新一轮区域经济合作浪潮,如美国提出的跨太平洋伙伴关系协定(TPP),俄罗斯倡导的“跨欧亚发展带”等。中国要加强与世界各国特别是亚太国家经济合作,就要提出新的战略构想﹣﹣“一带一路”倡议。

【共享发展】材料四:共享不只是理想,而有实实在在的内容。这就是以推进社会公平正义为前提,以推进扶贫脱贫、缩小收入差距为抓手,以推进区域、城乡基本公共服务均等化为保障,以推进共同富裕为目标。
