Abstract—This paper explores the alternative relationship between agricultural factors and conducts the discussion of technology progress bias. The result shows an alternative trend in the long term between the elements of the physical capital on the timeline. The replacement ability of capital for land has been improved because of human capital of the labour and the elasticity of substitution of human capital for chemical fertilizer has been showed higher(>1) since 1990, which implicates that the role of human capital cannot be ignored. Agricultural technology in China is demonstrated a changed bias after the introduction of human capital: from land-intensive agriculture to material capital (mechanical power and fertilizer) intensive gradually, and machinery technology progress is faster than the fertilizer. Technical progress of China's agricultural sector shows a capitalintensive type. The main reason is the substitution relationship between the agricultural material capital and human capital, rather than a complement one. China's agricultural production is not the function of agriculture human capital investment or skill-bias technological progress, which is a kind of economic technology phenomenon related to the not fully developed growth stage with the labour-abundant situation. 
Index Terms—substitution elasticity, human capital, technological progress type, skilled-bias
