简介:根据中国工程机械工业协会的统计,去年我国工程机械行业的总产值为380亿元,出口4亿分美元,利润为4亿元。从整个行业来看,利润是很低的,其主要原因是盈亏相抵的结果。下面我就具体谈谈我国工程机械行业的现状和面临的形势。

简介:据财政部消息,“十一五”期间国家将制定并实旖促进技术创新、鼓励企业成为自主创新主体的进口税收政策。重点包括:制订“振兴装备业进口税收政策实施办法”,在国家确定白喱大技术装备范围内,对国内装备业自主开发、制造重大装备所需进口的关键部件及原材料给予一定的进口税收优惠。同时,对相应的进口设备税收政策进行适当调整,原则上停止实施进口相应接机的免税政策。将原用于进口设备的税收优惠支出调接为对国内企业自主开发、生产设备的税收优惠支出,在不增加财政负担的情况下支持国内装备制造业的发展。对承担国家重大科技专项、国家科技计划重点项目或国家重大装备研发项目的企业,制定专项进口税收优惠政策。
