North American Industry Classification System
(NAICS)

• The mining sector (21)
• It is divided in
• 3 subsections
• 5 branches
• 10 sub-branches
• 31 activity types.

Data Envelopment Analysis (DEA)

• The DEA method measures productivity and
  efficiency of industry activities
• DEA measures the productive efficiency
  considering all the consumables used.
• DEA can be defined as a mathematical programmed
  technique that allows the construction of an
  envelope, also named efficient border or
  empirical production function, from available
  data come from the object that is studied.

12
Efficiency indicators

• DEA allows the evaluation of the relative
  efficiency.
• DEA analysis is considered for each mining
  product, each country represents each one of the
  units (companies).
• In this analysis, we evaluated the technical
  efficiency, it demonstrates the capacity to
  maximize the production, starting from a given
  set of consumables it means to minimize the
  consumables starting from a given production.
• The value of this indicator has to be between 0
  and 1, being the value of 1 the maximum
  efficiency.

Conclusions

• This analysis yields very important data for the
  comparison of the mining industry of both
  countries
• The interesting point is that the data obtained
  can be compared with other countries of the globe
• The DEA analysis reveals that for USA, the
  efficiency shown for each state in various
  sub-branch does not displays a wide difference
• The same analysis for Mexico, the indicators
  present a considerable difference
