【摘要】：我國的乳制品企業(yè)不斷面臨來自國際乳品企業(yè)的壓力,大量的進口可能會對乳品企業(yè)造成沖擊。文章旨在通過乳制品制造業(yè)的市場勢力去衡量我國乳制品制造業(yè)的市場溢價,并實證檢驗影響市場勢力的核心因素。文章選用了新產業(yè)實證組織的方法去做實證研究,在實證結果的基礎上,對我國乳制品業(yè)的發(fā)展給予一定的支持,并提出相應的政策意見�；贖all在1959年提出的生產法的基礎上,Roger1995年對其進行了進一步的修正,本文選用了Roger修正后的模型來測度市場勢力,這一模型的好處在于消除了未觀測到的生產率以及直接用名義變量測度。本文使用工業(yè)企業(yè)1999-2011年的乳制品制造業(yè)的數(shù)據(jù)通過構建回歸模型來測度市場勢力。此外,在構建模型時加入了四個可能影響市場勢力的因素,所有權結構、進口滲透、產業(yè)集中度、企業(yè)規(guī)模。我國乳品企業(yè)在近二十年間的所有權結構隨著改革開放和國企改革的深入而不斷變遷,國有企業(yè)在乳制品業(yè)無論絕對數(shù)量還是相對比例都在減少,而私有份額則在大幅增加,外資企業(yè)的引入也開始增多。在市場結構方面,乳制品業(yè)的集中度呈現(xiàn)先上升后下降的趨勢,無論是CR4還是赫芬達爾指數(shù)都表明,集中度在2006年是達到最高。在乳制品進出口方面我國乳制品制造業(yè)呈現(xiàn)了絕對的貿易逆差,特別是奶粉等干乳制品,最近幾年呈現(xiàn)了飛速增長。通過分析了影響市場勢力的因素,包括產業(yè)集中度,所有權結構、進口滲透、企業(yè)規(guī)模等。結果表明,產業(yè)集中度與市場勢力在我國乳制品業(yè)表現(xiàn)為負相關關系,產業(yè)集中度帶來的成本效應可能高于市場勢力效應。企業(yè)私有化對市場勢力有促進作用,進口滲透對市場勢力呈正相關關系,企業(yè)規(guī)模對市場勢力的影響并不是很明顯。
[Abstract]:Dairy enterprises in China are under constant pressure from international dairy enterprises. A large number of imports may impact dairy enterprises. The purpose of this paper is to measure the market premium of China's dairy industry through the market power of dairy industry, and to test the core factors that influence the market power. Based on the empirical results, the paper gives some support to the development of dairy industry in China, and puts forward corresponding policy suggestions. Based on the production law proposed by Hall in 1959, Roger1995 was further revised. In this paper, Roger's modified model is used to measure market power. The advantage of this model is that it eliminates unobserved productivity and measures directly with nominal variables. This paper uses the data of the dairy industry of industrial enterprises from 1999 to 2011 to measure market power by building a regression model. In addition, four factors, ownership structure, import penetration, industrial concentration and enterprise size, are added to the model. With the deepening of reform and opening up and the reform of state-owned enterprises, the ownership structure of dairy enterprises in our country in the past 20 years has been constantly changing. Both the absolute number and the relative proportion of state-owned enterprises in the dairy industry are decreasing, while the private share is increasing substantially. The introduction of foreign-funded enterprises has also begun to increase. In terms of market structure, the concentration of dairy industry increased first and then decreased. Both CR4 and Hefendal index showed that the concentration reached the highest level in 2006. In the aspect of import and export of dairy products, China's dairy manufacturing industry presents an absolute trade deficit, especially dry dairy products such as milk powder, which has shown a rapid growth in recent years. Through the analysis of the factors affecting market power, including industrial concentration, ownership structure, import penetration, enterprise size and so on. The results show that there is a negative correlation between industrial concentration and market power in China's dairy industry, and the cost effect brought by industrial concentration may be higher than that of market power. The privatization of enterprises promotes the market forces, and the import infiltration has a positive correlation with the market forces. The influence of enterprise size on the market forces is not obvious.
