有四个变量,year partner commodity valuestep1:每年的partner的同一commodity的value加总,得sumvalue1
step2:对每年的partner的相同commodity,得sumvalue2
step3:经过处理后,剩下,year commodity sumvalue2。
将commodity分为五组,如group1包括11、12,group2包括14、22,group3,group4,group5
根据五组分类,将sumvalue2加总。
不知这样是否表达清楚了。
我试着写了一下。麻烦指教下。没有想好如何处理第一、二步,还是我想的步骤有问题。多谢
sort year partner commodity value
egen sumvalue1=total(value),by(year partner commoditycode)/*把相同编码的value值加总*/
duplicates drop sumvalue1, force/*在处理完上一步后,如何删除new_var中的重复数据*/
sort year partner commodity sumvalue1
recode commoditycode (1 11 22 25 347=1) (12 14 23 24 35 =2) (281 689=3) (611 612 851 =4) (642 899 =5) (781 782 783 784 785 =6) (266 267 882=7) (711 873 884 885 951=8) (716 718 778 =9) (524 881 =10), gen(group)
/*根据技术水平加总*/
sort year group
