【历史—选修1:历史上重大改革回眸】

材料:  卷烟税在世界各国均为优质税源,莫不带来巨额收入。卷烟作为消费品在近代以来输入中国,最初数量甚微,海关也来将烟草列入独立税种。第二次鸦片战争中列强以进口烟草为在华洋人日用品为由,将其划入免税之列。而北洋时期,占据国内大半卷烟市场的英美烟公司担负中央正税不过7.5%,再加上英美烟公司经常通过一次性购买卷烟税印花或包税的手段减免部分税款,其实际税负只有2.5%~3%。而当时最大的民族烟厂南洋兄弟烟草公司,其原料进口时除纳进口正税及子口半税外,产品销往各地仍需缴纳“营业、畅销、厘金、杂捐、附加等税”,“负担即重,成本加多,虽出品优美,诚难与外贸竞卖”。除中央正税外,各省地方政府间有征收销场、落地等税,但征收标准也轻重多寡,各不相同,设置税率之标准亦不一致,或以容器为准,或以货量为准,或以货品为准,或以卖价为准,或以商铺为准,卷烟税制极其混乱。1915年5月,北洋政府为统一卷烟税制,扩充财源,决定实施烟草专卖。中央又将田赋、盐课、关税、厘金、烟税、印花税、契税等十七项优良税源列为中央税,仅将田赋附加税、牲畜税、粮米税、戏捐、车捐扽杂税杂捐划给地方,造成“国重省轻”的失衡局面。北洋时期,地方多为军阀主政,除教育、实业等消耗外,巨额军费成为重中之重,地方财政常常捉襟见肘。加之派系林立,政争激烈,内阁更迭频繁,由于出身与所属派系不同,各自主政时期财政整理目的和政策大相径良。
