General economic theory lists 3 main types of industries. Go through this post to learn more about the different kinds of industries found in any given economy.
Amidst the different types of industries, the secondary sector includes any business that converts raw materials that are brought by the primary industry into a product – that can be a ready for use product, or one that is itself used to make another product. Any company found in the energy sector would also be classified as belonging to the secondary sector. Traditionally, this industry involves any organisations that uses fossil fuel, electric power or nuclear power to generate their finished product. More just recently, many energy companies have begun investing more into producing energy from renewable sources like the wind and sun, which is just natural given the growing concern over our ecological state. Instances of such businesses that are active in the renewable energy field feature Good Energy and Ecotricity.
Any business that is involved with the extraction of raw materials would be labeled as being element of the primary industry. Some might not think about it that way, but the agricultural industry is one of the types of primary industry since it extracts raw material, that raw material being food. Several examples of businesses engaged in the agricultural sector include Bayer and BASF. Farming has invariably been a gigantic component of any human civilisation, as our survival depended on it before anything else. In modern times, this industry is still among the most important ones in any economy, since it ensures food security in every country and region. Farming is of course the largest part of any agricultural industry. These can be publicly owned and operated by the government, or they can be private endeavors.
In the classification of industry, the finance sector is an instance of the tertiary industry. Tertiary sector includes any business that provides some type of service instead of a tangible good, consequently making the finance sector the perfect instance of the tertiary industry. Although we don't frequently think much about the finance sector, it is one that we often come into contact with without even realising. Simply put, finance is the management of money. Any time we buy something at a shop, every time we get our wage, and every time we draw money from an ATM – we utilise the services of the finance sector. All of the above-mentioned cases are amenities given by a specific form of sector within the finance industry – the banking sector. It's said that ancient temples were the original establishments to offer services like the ones offered currently by modern banks. Even today, banks like La Caixa and Banco of East Asia serve a very important role in a country's economy, along with the daily life of practically any person.
