Replication package. The March 9 updated version includes the following minor comments from the data editor: 1. Information about the hardware and computational time for the analyses to the readme file 2. Code "set varabbrev on" to the do file Code for data construction.do 3. We use the full name of a variable instead of the abbreviation in Code for data construction.do,复现包。3月9日更新版本纳入了数据编辑人员提出的如下小幅修订意见： 1. 将本次分析所用硬件配置与计算耗时相关信息补充至自述文件（readme）中； 2. 在`Code for data construction.do`文件中添加代码"set varabbrev on"； 3. 在`Code for data construction.do`文件中，统一使用变量全称而非变量缩写。
