Do multinational corporations play a positive role in today's world? Some say that multinational corporations should play a positive role, but they failed to do so. Because they just think their own profit and don't mind local people. But I think multinational corporations today do their best and play a enough positive role. One of the reasons is that multinational corporations investigate the local people's demand and try to adjust their request. That is, cultural diversity is very important business success factor. If they lose this factor, their business would not exist in local. The second reason is that multinational corporations certainly contribute to jobs of local people. In order to produce their products, they often set up factories and employ many local people. Multinational corporations also teach them their technics and knowledge. Finally, multinational corporations are very concerned about the environment in order to enhance their social responsibilities. Some companies contribute tree planting, air and water cleaning by donations for their certain portion of profit and so on. Because of these reasons, I think multinational corporations today certainly play a positive role in the world.
