 note = {This paper analyzes the cost structure of software industry in China using the translog variable cost function model in which capital stock is treated as fixed. The model is estimated by a cross-section data of Chinese software industry in 34 cities. The results show that the demand elasticity for software engineer is smaller than that for the other labor, but software engineer labor and ordinary labor are still substitutable. Regarding economies of scale, larger companies do not exhibit scale economies in the short-run while smaller companies enjoy scale economies. This is because in larger companies, the contribution of software engineer labor is small. Larger companies recover scale economies in the long-run by taking advantage of substantial contribution of capital. However, Chinese software industry fails to be optimal in the long-run because of shortage of capital stocks. Also, national companies are found to be more efficient than individual companies in production of software.},
