中文摘要：

技术进步偏向性取决于技术进步收益率、要素稀缺性和要素相对生产率的增长率。通常技术进步偏向性使资本和技能型劳动生产率增长更快，资本和技能报酬更高并导致收入分配结构失衡。技术进步资本偏向性及其偏向程度加深，资本报酬更高且在收入分配过程中更具掠夺性，导致劳动收入占比下降并恶化劳动力市场地位。而技术进步技能偏向性使劳动力市场需求分化并出现技能溢价。若任凭市场经济自由发展，技术进步偏向性不断强化，技能型劳动需求增长、劳动收入占比下降和工资不平等现象持续存在，最终将阻碍一国经济可持续增长。

英文摘要：

Technical change bias is determined by technical change income rate, the factor rarity and the growth rate of factor relative productivity. Ordinarily the bias of technical change makes the marginal productivity of the capital or the skill grow faster, then leading to the dual differentiation of elements income distribution structure. The result is that, one is the capital bias of technology progress especially the more high level of it, which brings about the share of capital income becoming higher and having more power to exploit, and at the same time, makes the status of labor income distribution deteriorate and the proportion of labor income decline; the other is the skill bias and skill-labor at premium. All these mean if it share dechne and its status decline continuously, of technical change making the labor market differentiate makes the market economic growth free, the labor income which makes economic growth not sustaining.
