The proposition to promote the fusion of industrialization and transform the industry from large to strong” gave the directions of China from a “giant country of manufacturing” to “powerful country of manufacturing”. Equipment Manufacturing Firm (EMFs) are gradually playing an important role, which become an important support to regional economic growth and science and technology progress. So EMFs growth becomes an universal problem, and how to evaluate the growth of EMFs becomes an important step, especially to EMFs growth.
