沿用随机前沿分析模型,针对国有企业与外资企业生产技术的要素偏向指数,借助于超越对数生产函数分别进行了测算,并通过系统广义矩估计对两类企业生产技术资本偏向进行了影响因素分析,研究发现:无论国有企业还是外资企业的生产技术均偏向于资本,但是国有企业生产技术的资本偏向指数比外资企业要高得多;要素结构的资本化程度越强,生产技术的资本偏向度就越低,而行业竞争强度越大、研发创新投入比重越高,生产技术的资本偏向度则越高;同时,出口则会削弱国有企业与外资企业生产技术的资本偏向。
Following the stochastic frontier analysis model, the factor bias index of production technology of state-owned enterprises and foreign-funded enterprises was calculated and the excess production index was calculated respectively. The influencing factors of the capital bias of production technology in two types of enterprises were analyzed by system generalized moment estimation The research shows that whether the production technology of state-owned enterprises or foreign-funded enterprises are biased towards capital, the capital bias index of production technology of state-owned enterprises is much higher than that of foreign-funded enterprises; the capitalization of factor structure is stronger and the capital bias of production technology The lower the competitive intensity of the industry, the higher the proportion of investment in R & D and innovation, the higher the capital bias of production technology; the same time, the export will weaken the capital bias of the production technology of state-owned enterprises and foreign-funded enterprises.
