本文基于数据包络分析法构建全要素能源效率分析框架,利用中国工业部门35个行业1994-2007年的统计数据,对经济转型期间工业部门全要素能源效率进行分析.研究表明中国工业部门增长以能源低效为特征,工业部门全要素能源效率和技术效率都偏低,工业增长模式依旧粗放,重化工业化发展水平较低.为此,应建设节能降耗的技术创新激励机制,将能耗与环境污染指标纳入国民经济核算体系,改变政府垄断的能源定价方式,改革能源管理体制等.  相似文献

改革以来,中国工业化的一个重要特征是工业部门产出迅速扩张的同时,它吸收的就业增长明显滞后.笔者发展了一个理论模型和相应的统计分析框架,从理论和实证两个方面考察了工业化的两个基本推动力量--技术创新和资本积累对我国工业化进程中产出和就业增长的影响.我们发现,资本积累没有对工业部门产出和就业增长的趋势产生统计上显著的影响,然而,它是推动1990年之前工业部门产出增长以及1978年~2004年间工业部门就业增长的主要力量;技术创新的劳动节约偏向决定了工业部门就业增长明显下降的趋势,并成为1990年以后工业部门产出增长的主导力量.  相似文献

本文基于两部门经济增长模型构建工农业内生增长模型,考虑了工业与农业生产率差异和工农业溢出效应,分析在有限的资源条件下工业部门资源配置优势以及全社会经济增长影响因素。研究发现:工业部门因其生产率优势、溢出效应而具有资源配置优势,但农业发展滞后也会限制工业资源配置优势扩大;同时,全社会经济增长受工业增长、工业对农业溢出效应及农业增长共同影响。因此,工农业既存在资源竞争,又存在协调发展需要。  相似文献

基于2005~2013年工业水污染物治理投入与除去数据,利用污染当量法和DEA模型,首次计算了中国38个工业部门水污染的治理效率。结果表明:总体治理效率较低,不同部门的水污染物治理的投入和去除状况、水污染治理效率差异明显;18个工业部门具有DEA相对有效,但其中一些重要工业部门的水污染物排放量大,加重了排放区域的环境污染;20个工业部门水污染治理存在DEA无效,其对环境的污染亦在加剧;15个工业部门的水污染治理效率在不断下降。主要产业部门的水污染治理效率主要依靠技术效率改善来支持,而技术创新的支持较弱。最后,针对各部门特点提出了对策建议。  相似文献

瓦尔拉斯把资本形成方程引入一般均衡体系后出现了内在的不一致性,从而在异质资本品的假设下,一般均衡体系只存在“差别利润率”。在斯拉法体系中,不同的资本品部门却拥有“统一利润率”。两种类型的利润率体现了两种均衡体系的对立。与“差别利润率”相联系的一般均衡体系只研究一般生产过程中的资源配置,体现技术关系;而与“统一利润率”相对应的斯拉法体系则涉及特定市场经济关系下的总量分配,体现社会关系。而后者才可以更好地解释市场经济中的现实问题。  相似文献

In the literature investigating the impact of uncertainty on short-run and long-run investment, most authors have used a log linear profit function. This functional form has been generally considered a reasonable approximation for a more general one and has the advantage of providing closed form solutions for both short-run investment rule and long-run rate of capital accumulation. In this paper, we consider the profit function for the case of a monopolistic firm facing a linear demand function with additive shocks. Under this assumption, analytical solutions, for both short-run investment rule and long-run rate of capital accumulation, are not available. We then 1) propose an analytical approximation of the short-run investment rule and 2) show how such approximation can be used in order to derive the corresponding i) steady-state distribution of the optimal stock of capital and ii) the long-run average rate of capital accumulation. Finally, we compare the long-run rates of capital accumulation calculated under both profit function specifications. We find that, within a plausible range of parameter values, the two rates are significantly different. Hence, we conclude that the choice of a log linear functional form has a non-trivial impact on the magnitude of the long run rate of capital accumulation.  相似文献

The objective of this article is to evaluate empirically the profit rate persistence in the case of the Greek manufacturing industry (1963–88). More specifically, we address ourselves to two questions: first, do industrial profit rates eventually converge on a common rate? and secondly, what are the factors that affect the speed of adjustment of industrial profit rates? Our results suggest: a high persistence of profit rates for most industrial sectors; a generally high permanent component of the profit rates with substantial variations among sectors; and a similarity with other studies of industrialized countries with regards to the factors (concentration ratio, advertising intensity, export intensity, capital intensity etc.) affecting the speed of adjustment.  相似文献

The purpose of this paper is to estimate and investigate the behaviour of Marx's rate of profit for the period 1919 to 1981. The components of this rate, viz. constant and variable capital which are consistently defined as stock variables, surplus value, organic composition of capital and rate of exploitation, are estimaed for two sub periods for the manufacturing and the corporate enterprises sectors respectively. The rate of profit does not exhibit a discernible trend movement over the period of observation. However, it is subject to pronounced pro-cyclical variations. A similar picture emerges for the organic composition of capital and the rate of exploitation. The results are critically evalualed.  相似文献

Summary Profit data which are derived from historical cost accounting (which is the dominant accounting method in most countries) are biassed upward when inflation occurs. The reasons for this bias are based on the concept of capital maintenance (in whichever variation) which pervades accounting standards and hold that the surplus of revenue over (historical) cost has to be split into two parts: One has to be set aside by the firms in order to assure reproduction at the previous period's level (going concern assumption) (=fictitious profit) and only the rest is actual profit which can be used for distribution, debt retirement, net investment, tax payments, etc.In this study various capital maintenance concepts are related to the corresponding profit concepts and thus to the corresponding inflation accounting methods. Which profit concept is use depends on what the concept is supposed to measure. A large part of the (very heated) discussion on inflation accounting methods is shown to be due to a confusion about which profit concept is supposed to result from the calculations.This study uses Austrian industry corporation accounts to present various accounting methods and profit concepts with and without inflation accounting. The dominant profit concept in this study attempts to measure thesocial return to total investment. Thus accounting data are adjusted to eliminate inflationary effects in fixed capital, inventories and net monetary capital. The resulting real profit rates show a significant downward trend over the last twenty years, but remain positive even during the recession of 1974/75. When contrasted with a real capital market interest rate, industry profit rates exhibit a significantly better performance.  相似文献

The purpose of this paper is to derive some interesting results on long-run equilibrium by considering entrepreneurs' capital accumulation behavior explicitly. Our framework is a two class, two production sector model in order to analyze the dynamic stability properties in the cases of Kaldor's saving assumption and Pasinetti's saving assumption. We shall introduce a further adjustment mechanism: the speeding up (slowing down) of capital accumulation in that sector in which the rate of profit is higher (lower).  相似文献

This paper seeks to determine whether, under bilateral monopoly, profit rate regulation induces an input price bias in addition to the well known Averch-Johnson capital intensity bias. Using a Nash-type employer-union, fixed bargaining power model, it is found that regulation may induce lower as well as higher wage rates. Similarly, when the two parties are respectively capital equipment supplier and user, regulation of the user's profit rate has an ambiguous effect on the equipment rental rate. In both cases the input price effect is shown to depend on the elasticity of factor substitution and on how demand elasticity varies with output.  相似文献

The paper sets out a one sector growth model with a neoclassical production function in land and a capital–labour aggregate. If the elasticity of substitution between land and the capital–labour aggregate is less than one and if the rate of capital augmenting technical progress is strictly positive, then the rate of profit will fall to zero. This result holds regardless of the rate of land augmenting technical progress: no amount of technical advance in agriculture can stop the fall in the rate of profit. The paper also discusses the relation of this result to the classical and Marxist literature.  相似文献

The purpose of this paper is twofold: to show how to measure profit efficiency in banking using a newly developed technique, and to use that technique to determine the effect of risk-based capital requirements on the profit performance of US banks. The measure of profit efficiency used captures deviations from profit maximization arising from technical inefficiency, caused by a lack of managerial oversight and allocative inefficiency, which is caused by managers choosing a nonoptimal mix of inputs and outputs. A leverage ratio constraint and a risk-weighted capital ratio constraint are explicitly included in the model, which allows identification of the effect on profits of those constraints. The techniques are applied to random samples of US banks for 1990, 1992, and 1994. The results indicate that allocative inefficiency is a larger source of profit loss than technical inefficiency and that the risk-based capital standards have a significant effect on bank allocative efficiency.  相似文献
