Empirical Research, Communications Equipment Companies Listed Company X-efficiency Of Its Main Influencing Factors

With the launch 3G, TD-SCDMA industrialization process accelerated, WCDMA and cdma2000 technologies and markets mature in China, Chinese communication equipment manufacturing enterprises as the communications industry, building structure and the main provider of infrastructure, greatly changing communications industry impact will be more broad market prospects, it is to give attention and analysis. In this paper, communication equipment manufacturing enterprises in China listed companies and their X-efficiency of the main factors of analysis and research through the non-parametric empirical methods to communication equipment manufacturers listed companies to measure and X-efficiency analysis, identify the communications equipment manufacturer X efficiency of the main factors, then gives the direction of improvement, the domestic communications equipment manufacturers to provide reference to the healthy development proposals.This paper selects 29 listed companies in communications equipment manufacturing enterprises as a sample, using data envelopment analysis DEA approach to the number of employees, management costs, fixed assets, current assets, intangible assets and main business input cost index to net profit, Main business income and earnings per share for the output indicators measure the sample using DEAP2.1 software technology company for the period 2002-2008 the decomposition efficiency and technical efficiency index of pure technical efficiency and scale efficiency of computing communications equipment manufacturers listed companies allocative efficiency, and on this basis, communications equipment manufacturers obtained X-efficiency of listed companies. Found that communications equipment manufacturers listed companies in 2002-2008, the level of technical efficiency between a higher and more stable, but in 2007 there was a slight decline, may be related to the U.S. subprime mortgage crisis, there is a certain negative impact on the relationship, but integration of all samples changes in technical efficiency of enterprises, the majority of the sample enterprises technical efficiency remained unchanged or increased, so I think that led to decline in the average technical efficiency level of the main internal factor is the enterprise. Technical efficiency can be decomposed into pure technical efficiency and scale efficiency, pure technical efficiency and technical efficiency of the trend, as communications equipment manufacturers in China listed companies the size of the overall level of efficiency, which shows that most of the communications equipment manufacturing companies to achieve economies of scale, communications equipment manufacturers in China are basically at the scale of the effective phase. Allocative efficiency by internal resources, human capital structure and ownership structure of China's telecommunications equipment manufacturing companies 2002-2008, the allocation efficiency of the overall low level, which led directly to communications equipment manufacturers listed companies the value of partial X-efficiency low, indicating that China's telecommunications equipment manufacturing companies in the resource allocation, there is still a great combination and use of space for development.This conclusion on the basis of the above combined with communication equipment manufacturing enterprises Woguo own characteristics, presents six main factors affecting the efficiency of X, namely, company size, ownership concentration, technological innovation, market share, asset management capabilities and tax subsidies. To the six factors as independent variables, measured out the text before the X-efficiency value of the dependent variable, the establishment of an econometric model, the regression analysis. The results show that communications equipment manufacturers in China X Efficiency in descending order of significance for the return on total assets, ownership concentration, the proportion of R & D personnel share of employees, government subsidies, total assets and market share. Total asset turnover and X efficiency became apparent positive relationship, than any other factor the largest influence, ownership concentration, share of R & D staff ratio, and government subsidies and the total assets and X is a negative correlation between the efficiency to illustrate the China Communications Equipment manufacturers listed company's development process, these factors have a negative impact to some extent, market share and communications equipment manufacturers X-efficiency of listed companies showed a weak positive correlation between the degree. Finally, measure the results and regression analysis based on the proposed increase communications equipment manufacturers in China listed companies X efficiency measures and suggestions. Including:raising the level of total asset turnover, adjusted equity ratio, increase research and development staff development efforts, and to remind the telecommunications equipment manufacturing firms at the process, to reduce dependence on government subsidies, should be adopted to strengthen the research capacity of its own and operational capacity to improve the company's performance level. Do not blindly expand business scale and market share, should focus on the efficiency of enterprises based on firm size and market share expansion appropriate.
