Indústria Transformadora e sua Classificação
Fundamental Concepts of the Manufacturing Industry
The manufacturing industry, referred to in technical terms as "indústria transformadora," is a primary component of the secondary sector of the economy. This activity centers on the large-scale transformation of raw materials into usable goods. These outputs are categorized into two main streams: finished products, which are ready for immediate final consumption by end-users, and semi-finished products, which are intended for intermediate consumption as inputs for subsequent industrial processes.
The Strategic Importance of Industrial Activity
The manufacturing industry is considered a cornerstone of modern economic systems for several critical reasons. Firstly, it facilitates the essential transformation of raw materials into usable products for general consumption. Secondly, it is a significant generator of employment, creating numerous "postos de trabalho" (jobs) across various skill levels. Thirdly, industrial activities are responsible for the movement of massive amounts of capital, circulating wealth through national and international markets. Fourthly, the presence of industry acts as a catalyst for other economic sectors, incentivizing growth in services, logistics, and primary resource extraction. Finally, the industrial sector is a primary driver of progress, as it constantly stimulates technical, technological, and scientific innovation to improve efficiency and product quality.
Global Trends and the Deindustrialization Process
In recent years, a notable downward trend has been observed in the contribution of industrial production to the overall wealth of several nations. This phenomenon is known as the "processo de desindustrialização" (deindustrialization process). This shift typically occurs in countries with more developed economies where other sectors of activity, particularly the tertiary sector (services), are economically more valued and see higher growth rates compared to the secondary sector. This shift represents a structural change in how wealth is generated in post-industrial societies.
Statistical Observations on Global Industrial Wealth
According to data sourced from The World Bank, the percentage of the global Gross Domestic Product (GDP or "Produto Interno Bruto") contributed by the manufacturing industry has seen fluctuations with a general downward trajectory over the last few decades. In , the industry accounted for approximately of the global wealth. By the mid-, between and , this figure hovered around and . A gradual decline continued through the following decade, with the contribution reaching a lower threshold by , dropping toward . These figures underscore the relative growth of other economic sectors in comparison to manufacturing on a global scale.
Classification Systems of Industrial Activities
The industrial sector is complex and can be categorized using several distinct criteria to better understand its structure and impact. The three most commonly utilized criteria for classifying industry are the destination of production, the weight or volume of the raw materials used, and the level of technology applied during the manufacturing process. These classifications help economists and planners understand the resource needs and market roles of different industrial facilities.
Industrial Categorization by Production Destination
When classifying industry by the destination of its production, two primary sub-categories emerge: final consumer goods and intermediate consumer goods. The "indústria de bens de consumo final" (final consumer goods industry) produces items designed specifically to satisfy the immediate needs and demands of the market and individual consumers. Key examples of this include the production of household appliances ("eletrodomésticos"), apparel and clothing ("vestuário"), furniture ("mobiliário"), and various food products ("bens alimentares").
Conversely, the "indústria de bens de consumo intermédio" (intermediate consumer goods industry) focuses on manufacturing products that are not yet ready for the final consumer. These goods will undergo further industrial transformation and serve as the raw materials for other manufacturing sectors. Notable examples of this category include the metallurgical and steel industries ("indústrias siderúrgicas"), which produce iron and steel for construction and machinery, as well as the paper pulp ("pasta de papel") and textile ("têxtil") industries, which provide the base materials for paper and clothing manufacturing respectively.
