Then, in order to measure their activity its
necessary to update
- The instruments of measurement
- The organization structure for measurement

Characteristics of the economic units
Manufacturing Establishment
It is the economic unit which in a single
physical location, built in a permanent place and
surrounded by fixed constructions and
installations, combines actions and resources
under the control of a sole property or
controlling unit to perform mainly activities of
transformation, fabrication, assembly or
processing of one or several products totally or
partially on its own or for others.
6
Characteristics of the economic units
Maquila Establishment
It is the economic unit which in a single
physical location, built in a permanent place and
surrounded by fixed constructions and
installations, and under a sole owner or control,
performs for others industrial or services
processes for the transformation, assembly or
repair of temporarily imported merchandise which
result in the production of goods and services
for exportation and/or for sale in the national
market.
7
Characteristics of the economic units
Maquila for Exportation
Its the generation of goods and services with
temporarily imported raw materials which belong
to a third party, intended for exportation, under
the maquila program established by the Mexican
federal government to promote external trade. An
enterprise may act as the main plant and another
as a branch or else be an independent plant and
still perform the maquila process under the
program of Incentives for Exportation which
offers fiscal advantages to the economic units
which decide to become affiliated.
8
Characteristics of the economic units
Maquila for Exportation Establishment
It is the maquila establishment which has its
affiliation to the Maquila for Exportation
Program issued by the government.

Measurement of the Manufacturing Activity

- The Monthly Survey of the Manufacturing
for Exportation Industry (EMIME).

Measurement of the Manufacturing Activity
The EMIME is an important source of
information for the commercial balance, for the
exports

Importance of the information from the
Surveys for the System of National Accounts of
Mexico
The industrial surveys provide the fundamental
input for the measurement of the Gross Internal
Product (GNP) of the country.
With industry accounting for approximately 21 of
the GNP, the maquila industry and the
transformation industry are added in a weighted
way to measure the contribution of the industrial
sector.
A change in the conformation of these two
segments would generate changes in the calculated
amount of the GNP.
15
Situations affecting the Business Directory
Sources of the Industrial Sector
I. The economic censuses, employed as a sampling
frame for the EIM II. The directory of the
maquila for exportation enterprises of the
National Department of Economics, which is the
sampling frame for the EMIME
16
Situations affecting the Business Directory
Main changes in the directories
Changes in the Type of Activity
Appearance of Auxiliary Maquila Units
Changes in Program
17
Situations affecting the Business Directory
Changes in the Type of Activity
The economic unit produces goods or provides
services which are different
Continues in the same activity class
yes
No movement in the directory
no
Movement in the directory
The statistics are altered
18
Situations affecting the Business Directory
Appearance of Auxiliary Maquila Units
Enterprises which form establishments for
producing, under the maquila system, parts of the
production of the main enterprise
Its added one or more units in the directory
Changes in the measurement of the economic
activity
19
Changes in Exportation Maquila Program
The e.u. continues in exportation Maquila Program
EMIME Directory
The e.u. belongs to
The e.u. is passed to EIM directory
no
EIM Directory
yes
The e.u. continues in EMIME directory
The e.u. adopted the exportation Maquila Program
no
The e.u. continues in EIM directory
yes
The e.u. is passed to EMIME directory
20
An hypothetical example
Two enterprises belonging to the EIM with one and
two establishments respectively and within the
CMAP activity class 382302 Manufacture, assembly
and repair of equipment for information
processing adopted the Program of Maquila for
exportation.
Then, these establishments were moved from one
directory to the other.

Conclusions
The definition of the dominions of study for a
permanent measurement of the economic activity
must be based in the characteristics of the
productive process of the economic units and not
in considerations of administrative type such as
the government support programs for some type of
activity.
29
Conclusions
There are no essential differences between the
productive process of a manufacturing
establishment and a maquila establishment, so the
latter should not be considered as excluded
segments for the measurement of the sector
activity.
30
Conclusions
An integral measurement of the industrial sector
makes it easy to visualize the dynamics of the
different segments of activity and the
relationships between them.

Epilogue
In November 2006 the new Decree for the
Manufacturing, Maquila and Services of
Exportation Industries know fot its initials as
IMMEX, was published.
In compliance with this new decree, starting in
2007 the Maquila for Exportation Industry
statistics are no longer captured as a support
program of the National Department of Economics.
The INEGI also measure the economic activity of
the establishments in the IMMEX program,
presenting results in early 2008.
The affiliation of a establishment to the program
does not modify its condition of belonging to
the universe for the manufacturing industry,
measured by the EMIM
