搬运工在解释国家角色方面的作用将在本节中解释，举例说明将有助于解释这一事实。可以采取汽车产业的例子：中国教育程度低，这是他们有不熟练的劳动力的主要原因。他们希望聘用来自美国，英国，德国和日本等国家的熟练劳动力（Bellak and Weiss，1993）。与美国，英国，德国和日本这些国家相比，他们要求欠发达国家和发展中国家的劳动力，因为那里的劳动力充足而且便宜。日本的丰田公司指出，他们在研发方面的投入比任何国家或公司都要多，因为他们想保持竞争优势（Baldwin，1993）。波特五力只讨论了以下事实：
The role of porters downplay in explaining the role of the state will be explained in this section and example will be provided that will help in explaining this fact. Example of automobile industry can be taken: China has low level of education and this is the major reason that they have unskilled labour. They want to employ skilled labour from other countries like US, UK, Germany and Japan (Bellak and Weiss, 1993). In comparison with these countries US, UK, Germany and Japan they are asking for the labour from underdeveloped and developing countries because the labour over there is in abundance and cheap. Toyota of Japan has noted that they have invested on research and development more than any country or company because they want to maintain the competitive advantage (Baldwin, 1993). Porter five forces only discussed about the following facts:
1.Threat of new entrants: in this attribute the discussion is based on the higher fixed costs that are present in the market, loyalty of the major brands in the country. Today every market is looking at the competition and this competition is getting intense because of the changing demands of customers (Garelli, 2003).
2.Power of the suppliers: for some products the power of suppliers is higher because not everyone is willing to supply the products. This aspect explains the importance of suppliers for the industry and products (Grant, 1991).
3.Power of customers: commonly in every market the power is in the hands of the customers because they have are the ones making and breaking the situation.
4.Threat of substitutes: this is a major threat that has captured most of the markets in different countries. These markets have gained the competitive advantage of most of the companies (Ketels, 2006).
5.Competitive rivalry: this is the major impact and this is present in most parts of the world.
