particular that of the European Union for Portugal and Spain, an important vector, since
it regulates a large part of the transactions under study. Section 4 is essential within the
scope of this article, as it presents the survey carried out on Portuguese SMEs in their
internationalization to Latin America, refers to the methodology that was followed, shows
the results that were achieved, commenting on them and extracting a first set of
conclusions about the process. Finally, Section 5 summarizes the main conclusions and
raises some issues for further research.
2. Theoretical Framework
Considering the importance that internationalization processes have assumed in recent
decades for most economies, it is necessary to present the theories that explain them,
in particular with regard to its most significant flows and of greatest impact: international
trade and foreign direct investment. This is what we do now, in an abbreviated manner
and focusing on the essential.
Basically, according to the main theories on trade, the internationalization of economies
goes through a process that leads to their specialization in certain products, based on
the advantages that the country has, creating conditions for the exchange between
commercial partners, through a greater efficiency that leads to an increase in output
(with the same level of resources) to be shared. This approach was central to the classical
authors of economic science, namely Adam Smith in his work Wealth of Nations (1776)
whose lens used what would become known as the Theory of Absolute Advantages.
According to Smith, countries should specialize according to their lower cost production
(measured by labor cost, the only factor of production considered by these authors).
However, considering two countries, this theory states that if one of them had lower costs
in all relevant productions, it would have no interest in doing trade with the other and
there would be no international specialization. David Ricardo will overcome this limitation
in his reference work Principles of Political Economy and Taxation (1817), through the
Theory of Comparative Advantages, which reformulates the question in other terms
justifying trade even if one of the countries had all the absolute cost advantages in the
production of goods. Rather, countries should specialize in products that have the lowest
relative (and not absolute) cost, focusing on what they did most efficiently and opening
up a wider space for international trade based on specialization with mutual benefits for
the parties involved. Later, John Stuart Mill completed the contribution of the classical
authors, drawing attention to the Law of Reciprocal Demand, that is, the exchange ratio
is dependent on the reciprocal strength of the demands of each country in each product.
Although it is not the aim of this article to analyze the issue in depth, naturally, the
positions of the classical authors have been subject to much criticism over the past two
centuries; for example, specializing in one or another type of goods can have completely
different consequences in the long run (for illustrative purposes, see that certain products
correspond to a logic of increasing returns while others are in a decreasing returns drive,
that is, in the long run the specialization process led to its ultimate consequences, may
produce completely different results, i.e., unequal, as it was stressed by many authors,
such as Reinert, 2007). In any case, classical theories remained a major benchmark for
the internationalization process, both in terms of analysis and economic policy, although
many of its initial assumptions have also been relaxed and/or changed.
On the path opened by the classical authors, one of the main developments was the
emergence of the neoclassical theory of international trade during the first half of the XX
century, well exemplified by the Heckscher-Ohlin Theorem, which later had several
extensions. These authors gave up one of the basic classical hypotheses, considering two
factors of production, capital and labor, explaining the international specialization by the
endowment of each country in these factors. In the case of a greater abundance of one
factor (for example labor) relative to the other, the country should specialize in goods
