中国内地各省区1952—2009年实物资本存量估算 总被引:1,自引:0,他引:1
中国内地各省区的实物资本存量估算及相关研究一直是我国经济学界的研究热点.本文利用永续存盘法对中国内地各省区1952-2009年的实物资本存量进行估算.通过对比分析已有的研究文献,利用现有的资料与统计数据对永续存盘法估算每年实物资本存量所用到的几个指标:每年的投资流量、每年实物资本存量的折旧、每年投资流量的价格指数以及初始年份实物资本存量进行了详细的筛选与界定,并且对缺失的数据进行了研究与处理. 相似文献

中国基础设施资本存量估算 总被引:19,自引:6,他引:19
基础设施是国民经济赖以发展的基础。而深入考察基础设施对于中国经济增长的影响,依赖于一套完整的全国及省际基础设施资本存量数据。为此,本文在现有研究的基础之上,对基础设施投资范围进行了界定,并对官方统计数据进行了必要的补充和调整,进而通过永续盘存法分别估算了全国层面1953—2008年以及省际层面1993—2008年各年末的基础设施资本存量。 相似文献

对中国资本存量K的再估计 总被引:303,自引:12,他引:303
许多实证研究都要涉及到对资本存量K的估计 ,但是现有研究中对K的估计值存在较大的差异 ,从而也就影响了后续研究的准确性和可靠性 ,所以很有必要针对估计中国的资本存量K的现有研究进行一下再探讨。本文分别从五个方面详细探讨了测算K时所可能存在的问题 ,并根据自己的方法重新估算了中国的资本存量K的数据。 相似文献

中国实体经济资本存量与投资效率:1981~2009 总被引:1,自引:0,他引:1
本文考察了当前学者普遍采用的固定资本存量估算方法,在已有的文献基础之上,根据目前国内的最新统计数据,运用永续盘存法估算了1981~2009年中国实体经济部门的资本存量,并借此进—步从三个维度分析了1981年以来我国实体经济部门投资效率的变动状况,实证分析的结果表明我国实体经济部门的宏观投资效率持续走低. 相似文献

从本文研究结果来看,投资带来的资本存量快速增加是中国快速发展的重要原因,但是资本存量并没有传统研究估算的那么高,另外资本效能下降也是中国一个需要关注的现象。与传统研究不同,本文发现中国折旧变化并不是一个直线,而是分阶段逐步上升的,研究结果比较符合中国作为新兴市场国家的实际。 相似文献

We develop a forward-looking profit model to estimate the depreciation rates of business R&D capital. By using U.S. government data between 1987 and 2007, and the newly developed model, we estimate both constant and time-varying industry-specific R&D depreciation rates. The results comprise a set of R&D depreciation rates for major U.S. high-tech industries. They align with the main conclusions from recent studies that the rates are in general higher than the traditionally assumed 15 percent and vary across industries. The relative ranking of the constant R&D depreciation rates among industries is consistent with industry observations and the industry-specific time-varying rates are informative about the dynamics of technological change and the levels of competition across industries. Lastly, we also present a cross-country comparison of the R&D depreciation rates between the U.S. and Japan, and find that the results reflect the relative technological competitiveness in key industries. 相似文献

结合社会资本的概念分析了第三部门不同于政府、市场的作用,指出第三部门有利于促进社会资本的积累,解决公共物品的供给问题.在我国改革开放的过程中,第三部门的出现有其必要性与合理性;同时,又由于其特殊的生成方式导致了第三部门生命的脆弱性和人格的二重性,制约了其供给公共物品的效率. 相似文献

The purpose of this paper is to report estimates of capital input index classified by industries in China from 1981 to 2000. We estimate capital stock based on the perpetual inventory method, and then estimate the flow of capital service and capital service price consistently with the capital compensation in input-output table. In our study, we discuss various assumptions and adjustments made on the data and estimation implementation. 相似文献

随着知识经济的到来,人力资本已成为经济增长的关键因素。人力资本同物质资本一样,是企业生存发展不可或缺的要素;人力资本是企业风险的真正承担者,是企业财富的真正创造者,所以人力资本分享企业剩余是合情合理的。在实践中,人力资本股权化是对人力资本分享企业剩余的有益探索。 相似文献

This article discusses the treatment of fixed capital in the classical theory of price. Sraffa uses non-linear depreciation of ‘physical’ capital that equalizes all annual profit rates individually, but violates the proportionality of monetary machine value reduction and physical use-up on an annual basis. One alternative is to apply simple linear depreciation that has equal annual fixed capital costs. The key for consistency is that the internal rate of return on fixed capital investments throughout the fixed asset lifetime must be equated with the normal profit rate. A second alternative is to use ‘monetary’ capital, where the ‘correct’ amortization charges depend on the ability of the accumulated depreciation fund to earn interest. Among these valid alternative methods are the original proposals of Marx and Torrens, which were dismissed falsely and prematurely by Neo-Ricardian economists. These alternatives are shown here to imply fundamentally different prices of production. For all methods, the formulas for deriving amortization charges and fixed capital prices of all vintages are derived. The article also illustrates how the system of Sraffian price equations can be modified to incorporate these methods. 相似文献

This paper introduces a method of calculating physical capital stock figures in transition countries and derives data for Hungary. On the basis of international experience, we set investment and saving paths for future income levels. Confrontation of savings prospects of different sectors with investments needs leads to an economic policy analysis of the fiscal policy needed to catch up to 70 per cent of Austrian per capita income by 2030. 相似文献

We present a model of capital accumulation and technology adoption in a vintage-capital framework. The model is an infinite-horizon/infinite-dimensional optimal control model: the firm employs a continuum of technologies (a continuum of heterogeneous capital goods). Capital goods are technology specific, their technology is related to vintage and technology progress. The entrepreneur maximizes the profits obtained by employing a continuum of technologies under the assumption of constant returns to scale and bearing adjustment costs for gross investments. The diffusion of a new technology is established by allowing the entrepreneur to invest in vintage capital goods. 相似文献
