根据下列资料回答以下问题。根据国家统计局最新经济普查反馈的数据测算，2004年福建省的万元GDP能耗(可比价)为0．81吨标准煤／万元，现价为0．78吨标准煤／万元，在全国处于较低水平。导致福建省万元GDP能耗处在全国较低水平的主要原因是福建省轻工业比重较高。能源消费近70％集中在工业，在工业中轻工业耗能又较少。改革开放以前，福建省作为海防前线，加上福建省缺油、少煤，受资源条件的制约，国家较少安排重化丁业投资于福建省，福建省重工业基础较为薄弱，轻工业比重较高。改革开放以来，虽然经过多年努力，但福建省的重T业比重仍处在全国较低水平。2004年福建省规模以上工业企业中，轻丁业增加值的比重为47．1％，在全国处于较高的水平，在华东地区仅低于浙江0．2个百分点，分别高于江苏、山东12．9个和11个百分点；在全部工业增加值中，规模以上工业增加值所占比重福建省又处于较低水平，为72％，分别比江苏、山东和浙江低10．7个、10．4个和4．7个百分点，而规模以下T业企业中轻工业比重又较大。除了上海、江苏、浙江、安徽、福建、山东和广东外，2004年全国其他部分省、市规模以上轻工业增加值的和为()。
