Analysis On Corporate Efficiency And Related Factors Based On DEA Models

Efficiency is one of the key issues in economic research, but also one of production and operation management objectives. After reform and opening up, with the establishment of modern enterprise system and market-oriented as the main features, China's progressive economic reforms have made remarkable achievements. In addition, enterprise and enterprise efficiency, which are at the core of this reform, have become the current research focus.In this thesis, the author has systematically analysis the concept of enterprise efficiency and measurement methods, and also used Data Envelopment Analysis (DEA), based on the financial data of China's household electrical appliance industry publicly listed companies, detailed analysis technical efficiency, pure technical efficiency and scale efficiency of the household electrical appliance industry listed companies. Moreover, the author used Malmquist index, which is the measurement of dynamic changes of corporate efficiency, measured technological changes, technical efficiency indicators changes in recent years.The empirical part of the article, based on the theory of enterprise efficiency with the shareholders structure and market structure measured, measured different impact of the two factors. Finally, this paper forwarded improving ways in enterprise efficiency for household electrical appliance industry, and the study deficiencies.The study concluded the technical efficiency of China's household electrical appliance industry listed companies in 1999 -2006 has steadily increased mainly due to a purely technical efficiency improved. In addition, non-state-owned holding enterprises are more efficient than state-controlled-oriented enterprises; the enterprises controlled by the enterprises are also more efficient than sector holding enterprises. Malmquist index showed there were not obvious overall trend growth in China's household electrical appliance industry listed companies in 1999 -2006, and he annual average growed only 0.2%.The sub-regional study found that the central and western regions home electrical appliance industries listed companies are more efficient than the traditional industries in the eastern region. This innovation of this working paper is that the using DEA, the multi-input multi-output efficiency measurement model, not only analyzed the technical efficiency, scale efficiency, and so on of the samples, while using the Malmquist index reflecting dynamic changes of listed companies on the home electrical appliance industries each year, to a certain extent, making up for the shortcomings of the previous studies. In addition, this paper putting ownership structure and market structure in a two-dimensional space studied the two factors affecting enterprise efficiency differently and achieved the satisfied results.
