According to Du Ning's eclectic paradigm, there are four main reasons for enterprises to invest abroad: seeking resources, seeking markets, seeking efficiency and seeking strategic assets. The purpose of seeking resources is to obtain specific resources, such as natural resources, cheap labor and recently sought technology and management, marketing and organizational capabilities. As for the purpose of seeking market, it is to provide goods or services for the domestic market or regional market of the host country. The pursuit of efficiency is related to the concept, scale and risk management of scope economy. In the process of finding strategic assets, acquiring resources and strategic assets is the main goal for enterprises to strengthen their competitiveness and improve their skills in regional and global markets. These factors will be the dominant strategies for foreign enterprises to invest in other countries, but they are not the only ones.

"In Brazil and Mexico, empirical studies show that foreign investors will seek market or market attraction," said Lima Junior and Cuenca. Costa, matos and others believe that economic stability, trade liberalization and natural resources will become important factors for Brazil to attract foreign direct investment. In Mexico, the participation of NAFTA, economic liberalization, cheap labor costs and proximity to the US market are considered as the basic variables to understand the inflow of foreign direct investment into the country.
