What are the main characteristics of the Mexican economy?

Mexico is an "emerging market", "developing country" or "newly industrialized country" because although it is the eleventh largest economy in the world (USD$1,567 billion for 2010), it has an ongoing industrialization, where agriculture activities are still important but are rapidly being outpaced by industrial (specially manufacturing) activities. This means Mexico is not fully developed, as many regions within the country have a quality of life equivalent to those of Western Europe, whereas there are other regions with education, life expectancy and economic advancement equivalent to those countries found in Sub-Saharan Africa.
