中国服务业投资倾向与投资效率研究
发布时间：2018-09-03 11:11
【摘要】：本文对1996-2009年我国服务业的投资倾向和投资效率进行了研究。1996-2002年期间,我国服务业表现出资本劳动比例不断增加的投资倾向性,而且这种比例的构成建立在投资中资本要素的绝对值增加,劳动要素的绝对值先少量增加后逐渐减少的基础上,可以说在很大程度上资本代替了劳动。相比之下,2003-2009年期间我国服务业同样表现出资本劳动比例不断增加的投资倾向性。总而言之,1996-2009年间,我国服务业的人均资本年均增长率约为14%,行业整体表现出资本劳动比例不断增加的投资倾向。 同时DEA非参数法显示的相对投资效率结果表明,1996-2002年间,我国服务业整体投资效率偏低,其投资的平均技术效率仅为0.382,未达到DEA有效水平。规模效率低下是造成我国服务业整体投资效率偏低的主要原因。好在我国服务业投资处于规模收益递增的阶段,这些行业在完善资源优化配置的同时进一步扩大其投资规模有助于我国投资效率的提高。2003-2009年间,我国服务业整体投资的技术效率均值为0.43,较1996-2002年问0.382的均值所有小幅度增长。与1996-2002年不同的是,投资的纯技术效率是造成其投资效率偏低的主要原因。投资的纯技术效率低下说明我国服务行业在投资过程中管理水平较低,需要行业的从业人员提高人员素质以及岗位技能等。 1996-2002年间,资本密集型行业的投资效率和劳动密集型行业的投资效率均未达到DEA有效值。相比之下,资本密集型行业的投资效率每年都略高于劳动密集型行业,且呈上升趋势,而劳动密集型行业的投资效率趋于平稳变化不大。因此样本期间,服务业中要素投入倾向资本密集型行业,其投资更有效率。2003-2009年间,资本密集型行业和劳动密集型行业的投资效率也未达到DEA有效值。从整体上来看,资本密集型行业的投资效率呈下降趋势；而劳动密集型行业的投资效率呈上升趋势。但相比之下,资本密集型行业的投资效率每年仍高于劳动密集型行业。因此样本期间,服务业中要素投入倾向资本密集型行业,其投资更有效率。
[Abstract]:This paper studies the investment tendency and investment efficiency of China's service industry from 1996 to 2009. During 1996-2002, China's service industry showed a tendency of increasing capital-labor ratio. The composition of this ratio is based on the increase of the absolute value of capital factors in investment, and the absolute value of labor factors first increases a little and then gradually increases. On the basis of the decrease, it can be said that capital replaces labor to a great extent. In contrast, China's service industry also shows the tendency of increasing capital labor ratio during 2003-2009. In a word, the average annual growth rate of per capita capital in China's service industry during 1996-2009 is about 14%, and the industry as a whole shows the capital labor ratio. An increasing investment tendency.
At the same time, the relative investment efficiency of DEA non-parametric method shows that the overall investment efficiency of China's service industry is on the low side from 1996 to 2002. The average technical efficiency of China's investment is only 0.382, which is not up to the DEA effective level. In the stage of increasing returns to scale, these industries can improve the optimal allocation of resources and further expand their investment scale, which will help to improve the efficiency of investment in China. Pure technical efficiency of investment is the main reason for its low investment efficiency. The low pure technical efficiency of investment shows that the management level of service industry in China is low in the process of investment, and it needs the employees to improve their quality and post skills.
In 1996-2002, the investment efficiency of capital-intensive industries and labor-intensive industries did not reach the DEA effective value. In contrast, the investment efficiency of capital-intensive industries is slightly higher than that of labor-intensive industries every year, and shows an upward trend, while the investment efficiency of labor-intensive industries tends to change smoothly. In 2003-2009, the investment efficiency of capital-intensive industries and labor-intensive industries also did not reach the DEA effective value. In contrast, the investment efficiency of capital-intensive industries is still higher than that of labor-intensive industries every year. Therefore, factor input in service industries tends to be more efficient in capital-intensive industries during the sample period.
