The factor that can influence comparative advantage is differences in factors of production. Comparative advantage arises when countries can produce certain goods or services more efficiently than others due to variations in resources, capabilities, and production techniques.

For example, if one country is rich in natural resources, such as fertile land or minerals, it may have a comparative advantage in agriculture or mining. Conversely, another country with a well-educated workforce might excel in industries that require high levels of technical skill, like technology or pharmaceuticals. These differences determine the cost of production and, consequently, which goods each country can produce at a lower opportunity cost.

Factors like identical labor costs across nations, stagnant technological development, and equal levels of education do not contribute positively to the concept of comparative advantage. Identical labor costs would imply that no country has an edge in labor-intensive industries, while stagnant technological development would hinder any country from gaining a competitive edge through innovation. Equal levels of education would mean that the skill set is uniformly distributed across countries, which would diminish the scope for comparative advantage based on specialized education and training. Thus, the influence of differences in factors of production is vital in shaping comparative advantages among nations.
