I do not know what you exactly mean by territorial economy. If you mean that you look for spatial effects, than of cause spatial econometrics is the way to go.

Of cause you need data which cover a spatial dimension to do this, but than you go ahead and do it.

Rachid,

My knowledge of econometrics is that it is statistics and economics used in measurement  and they are applicable in many  areas where data is concerned and there is need to understand the relationship with the variables so I'm hesitant to agree with you that econometrics is not applicable, unless you clarify your question.

Best Erick Outa

Econometric analysis is useful in Territorial, regional, sub-regional, national, provincial, district, state, or cluster research. You only need to use the right data that reflect the intended scope of the study.

I do not see any problem, especially taking into account the recent acquisitions from spatial econometrics.

Thank you all for your feedback, I am reassured now!

I understand that you can aply for your research a new econometric topic: spacial econometric

I think now there is what called A Spatial Econometric Approach, you may find abet information related to this issues on:

please make your purpose plain.

if I rephrase my question

how can we identify clusters through the techniques of spatial economy? is spatial econometrics allows this identification?
