%X In the context of increasing energy shortages and degrading environment worldwide, researchers have been paying much attention to the degree of non-energy factors substituting for energy inputs, which is viewed as one of the most useful measures to conserve energy. However, a host of existing literature investigating the elasticity of substitution between energy and non-energy factors did not present the prior test for the production factor attribution of energy. There is little consensus regarding the degree and direction of interfactor substitution. Given that the in-plan energy prices controlled by the central government in China cannot reflect to the relation of supply and demand for energy and even the scarcity of energy resources, the cost function is rejected. On the other hand, the statistical errors of various data sets may lead to different conclusions for the causality between economic growth and total energy consumptionso it is indispensable to firstly test the causality between the two. Based on time series on economic growth, total energy consumption, capital stock, and labor over the period 1978-2008 for China, this paper applies vector error-correction model to test the causality between economic growth and total energy consumption. Empirical results indicate that there exists bidirectional causality between them both in the short and long run, and the change of capital stock and labor would impact on total energy consumption, respectively. Then we estimated the translog production function on GDP using the principal component approach, and calculated the elasticity value of energy-nonenergy factors substitution. Results suggest that the elasticity value of energy-labor substitution is 1.03, larger than that of energy-capital of 0.49. This implies that energy is substitutable by labor and capital, and labor substitutes for energy more easily than capital does during the study period. This finding is attributable to the typical pattern of labor-intensive industry depending on labor abundance. It is therefore concluded that the future industry should turn to capital-intensive sectors with the weakness of the advantage of labor. Finally, we investigated biases in technical changes measured by the proportional change in the marginal rate of substitution between any pair of energy-nonenergy factor inputs based on the estimated parameters. Results show that technical changes appear energy intensive since the reformation and opening, and then the presence of the technical change would have a positive impact on energy conservation. But the bias in the technical change among factor inputs can ultimately be convergent with the change in the industrial structure and the scarcity of capital and skill-labor.
