SAS一般变量命名不支持中文，在代码编辑器中运行如下代码即可实现以中文名为变量名。
option validvarname =any;
The intent of the VALIDVARNAME=ANY system option is to enable compatibility with other DBMS variable (column) naming conventions, such as allowing embedded blanks and national characters. Throughout SAS, using the name literal syntax with variable names
that exceed the 32-byte limit or have excessive embedded quotation marks might cause unexpected results.
SAS Name
You can use a name literal only for variables, statement labels, and DBMS column and table names.

When the name literal of a variable or DBMS column contains any characters that are not allowed when VALIDVARNAME=V7, then you must set the system option VALIDVARNAME=ANY.
Note: For more details about the VALIDVARNAME=ANY system option, see SAS Language Reference: Dictionary.
