The Ternary Marginal Extension of China’s Free Trade Zone Development

This paper attempts to establish a framework of upgrading mechanism in China’s foreign economic opening strategy in order to conclude the new connotation of upgrade for China’s foreign economic opening, with the basic starting point of ternary marginal extension on extensive growth, in the perspective of corporate heterogeneity theory. It also involves the new path of the transformation from “quantity” to “quality” regarding the amounts, models and locations of China’s foreign trade and investment. At last, this theoretical frame is complemented upon a case study of free trade zone and regional cooperation of Guangdong, Hong Kong and Macao.
