社会经济网络是一个经济、社会、文化俱乐部,将区域空间内企业的知识传递、创新活动、企业采购和销售等外部问题内部化,其存在减少了企业之间的交易成本,是一种介于市场和组织之外的第三种资源配置方式,是一种科斯制度的形式。这一理论对我国长三角地区的经济一体化和可持续发展有着重要指导意义。 Socio-economic network is an economic, social and cultural club that internalizes external issues such as knowledge transfer, innovation activities, procurement and sales of enterprises in regional space. Its existence reduces transaction costs among enterprises. The third way to allocate resources outside markets and organizations is a form of Coase. This theory has an important guiding significance for the economic integration and sustainable development of the Yangtze River Delta in our country.
