In this paper we apply a Data Envelopment Analysis (DEA) for measuring changes in total carbon emission efficiency between 1986 and 2008 across Chinese regions and then estimate driving forces of regional carbon emission performance (MCPI). A long-run relationship has been detected and the coefficients, estimated using Kao's method, are statistically significant mostly. Our results indicate the positive...
The article firstly describes C2R model and C2GS2 model of DEA method; secondly, it determines input and output indexes of Chinese equipment manufacturing and then uses DEA method to make positive measure of technical validity and scale validity about equipment manufacturing's input-output of 31 provinces and municipalities. Based on measure results, the article divides 31 provinces and municipalities...
There are great differences between DG TNCs and the transnational corporations of developed country (DC TNCs) in technological innovation field. This study analyze the situation of China's Haier Group, Korea's Samsung Electronics Co. and US General Electric GE by using Data Envelope Analysis methods, compared to the research and development input-output efficiency of these three enterprises. Both...
The paper constructed the data envelope analysis input and output index system of coal mine safety investment. Adopting the method to make the empirical analysis of a mining group safety investment efficiency, the results show: the group safety investment efficiency conforms to China coal industry regularity; 2005, it should reduce the number of workers, strengthen the safety management, at the same...
In order to investigate the interrelationship between risk and efficiency, based on the decomposition of risk into endogenous risk due to bad management and exogenous risk due to adverse environment, this paper introduces a modified measure of risk-adjusted efficiency by using a multistage data envelopment analysis (DEA) to estimate the real efficiency level for the 284 insurance firms in China from...
R&D (Research and Development) has been widely regarded as the major driving factor to promote the development of High-Tech industries. With the development of High-Tech industries for more than ten years, efficiency and productivity of R&D have become a critical issue in China. Accordingly, the main purpose of this paper is to evaluate R&D efficiency and productivity growth of 16 High-Tech...
In this paper, we calculate the coal efficient utilization ratio (CEUR) of 29 regions in China from 1995 to 2006, by applying data envelopment analysis (DEA) based on the regional own production frontier. And three inputs (labor, capital stock and coal utilization amount) and one output (GDP) are chosen for DEA. Results show that, the more developed area is, the higher CEUR is. The eastern, central...
This study uses data envelopment analysis (DEA) to evaluate the operational efficiency of 50 Chinese open-end funds, and makes a comparative analysis of selected fundspsila operational efficiency according to the fund size, investment type and investment style from the perspective of the overall and division. The result showed that bond funds had the maximum and stable average efficiency, hybrid funds...
This paper makes an demonstration measure on the 31 provinces' technical validity and scale efficiency of the fixed-asset investment by using the model of C2R and C2GS2 of DEA. According to the results, the 31 provinces are divided into different types whose characteristics of fixed assets investment are pointed out and measures of improving the efficiency of investment are raised. Two conclusions...
In recent years modern logistics has developed very rapidly after the logistic conception had appearing in china more than 20 years ago. This paper assesses the technology progress of the logistics in China on the base of DEA (data envelopment analysis) method. The principle of DEA method is illustrated, the feasibility and superiority of the DEA method when it is applied in evaluating the technology...
Theory of data envelopment analysis (DEA) was applied in the regulation of power transmission and distribution (T&D) in this paper. Firstly, relevant variables of T&D companies with similar production and operation status in China were classified and modeled. Then, references on regulation targets were provided for regulators through evaluating parameters of these companies in the DEA model,...
