需要と供給
One of the major factors influencing the need for networks is the globalization of the economy. Supply and demand are no longer local but global. The price of commodities is affected by the weather halfway across the world or by demand in developing countries. Production takes place wherever the assets and human resources can most effectively deploy. Professional services providers must be able to reach out globally to represent their clients everywhere in the world. Networks are the practical and cost-effective method to accomplish these objectives. Members of networks have access to other members who understand the local economic, legal and political factors.
