Stata：数量经济学命令介绍—cnuse命令更新一览表--即将发布
一、数量经济学命令介绍—cnuse
在数据分析的过程中，我们经常需要加载不同格式的数据文件。
为了简化这一操作，并方便下载调用计量经济学服务中心/数量经济学微信公众号推文数据以及网络数据等，为大家推荐全新的“cnuse”命令，它可以方便地从本地或在线来源导入多种文件格式。
下面我们将详细介绍这个命令的使用方法和新功能。
1. 命令名称
cnuse
cnuse命令部分源ado文件代码查看
2. 描述以及新功能
cnuse 是一个灵活的数据导入命令，支持从本地文件和在线 URL 导入多种格式的数据文件。
支持的格式包括 .dta, .csv, .xls, .xlsx, .txt, .zip, .shp等，大大增强了数据文件的兼容性。特别适合需要快速从远程位置下载并加载数据、文件的用户。
New：
cnuse支持导入.shp数据支持 .dta,.xls,.xlsx,.txt,.csv,.zip,.shp,.sav.等类型文件的导入、下载将支持 .r,.tex,.html,.log,.py,.md,.py.,.ipynb文件的下载调用将支持 .ado,.do,.smcl等Stata文件的下载、使用将支持 .pdf,.doc,.docx,.ppt,.pptx,.wmf,.emf,.tif,.png等文件
cnuse 菜单版操作界面
3. 重要新功能更新
智能文件识别：根据文件的扩展名，自动选择正确的导入命令。
格式支持扩展：除了常见的
.csv和.dta文件，cnuse还支持.xls/.xlsx电子表格、.txt文本文件、.shp形状文件，以及.zip压缩包等。自动解压缩：如果输入文件为
.zip，该命令可以自动解压并加载其中的数据。全面兼容网络数据：当本地找不到指定文件时，
cnuse会自动尝试从提供的 URL 下载文件。可以调用网络数据包括但不局限于Stata官网数据、 BC Economics Stata datasets
4. 案例应用
4.1 导入dta数据
4.2 导入Excel文件
4.3 导入csv文件
4.4 导入txt文件
4.5 导入shp文件
新功能添加以及修改ing，所以之前网络下载导入.shp 文件的版本忘记保存了，导致现版本导入.shp 文件仍有一些bug，继续测试中。
上述演示大概率为之前版本保存到本地后导入的，并非实际意义上网络导入的
4.6 导入zip压缩文件
4.7 网络数据下载调用
目前调用bcuse数据集已经支持不用加url选项，支持cnuse直接加上数据集名称
当然还是推荐使用官方命令Stata：获取《计量经济学导论》数据+教材答案
cnuse直接下载bcuse数据列表(后期更新后将支持不用加入逗号后面url选项)，详见图片所示：
直接调用本地数据
直接网络下载调用
