    Lao:
    too broad questions seldom usually receive few/no replies.
    Please provide the list with more details about your query: help others help yourself! Thanks.
    Kind regards,

      You need to follow Carlo's suggestion and the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.
      This may be what you want:

      bysort industry: egen totalsales=total(sales),
      g mktshare=sales/totalsales
