中国要发展,人才是关键

中国提出要大力发展装备制造、信息、生物技术、新材料、航空航天、海洋、金融财会、生态环境保护、新能源、农业科技、宣传思想文化等经济社会发展重点领域方面的人才。可以期待国家将会对IT业培训加大扶持力度。

下面是联合早报网相关报道:

 正在加速推进经济转型与引领国家进入新发展阶段的中国政府,提出中国在2020年加入世界人才强国行列的目标,强调加快人才发展是中国“在激烈的国际竞争中赢得主动的重大战略选择”。国内专家认为,这表明中国力图实现核心竞争力转向,使之从“人口”转向“人才”。

  中国政府前天发布首份《国家中长期人才发展规划纲要》(简称《纲要》),强调人才是中国经济社会发展的第一资源。

  以10年为限,《纲要》对于中国人才数量的提升定下一系列明确的战略目标,包括使人才资源总量从现在的1亿1400万人增加到1亿8000万人;人才资源占人力资源总量的比重提高到16%;主要劳动年龄人口受过高等教育的比例要达到20%,每万名劳动力中研发人员从24.8名增加到43名;高技能人才占技能劳动者的比例增长到28%。

  《纲要》还指明,中国要在装备制造、信息、生物技术、新材料、航空航天、海洋、金融财会、生态环境保护、新能源、农业科技、宣传思想文化等经济社会发展重点领域,建成一批人才高地。
