【摘要】：郵電通信行業(yè)引入的競爭機制形成了目前壟斷競爭的格局,一方面郵電通信行業(yè)價格管制逐漸放松,另一方面運營商通過價格歧視來實現(xiàn)更多的利益。前人的研究大多從定性的角度探討通信業(yè)價格歧視及其造成的影響,尚未直接測度價格歧視,同時也未將空間計量引入郵電通信行業(yè)價格歧視的測度中。 本文完成以下四項工作:其一,采用固定效應模型來測量中國郵電通信行業(yè)的價格歧視,并分析其運動態(tài)勢。其二,分析電信行業(yè)套餐資費的價格歧視,以此來佐證上述模型計量價格歧視的正確性。第三,引入空間計量模型,研究郵電通信行業(yè)價格歧視的空間布局。最后,分析郵電通信行業(yè)價格歧視和人均收入以及市場勢力的內(nèi)在關系。 研究結(jié)果如下:第一、根據(jù)固定效應模型,計量得出分地區(qū)郵電通信行業(yè)價格歧視數(shù)值,發(fā)現(xiàn)通信行業(yè)整體和電信行業(yè)的價格歧視程度逐年減弱,而郵政行業(yè)的價格歧視有增強趨勢。同時,郵電通信行業(yè)各地區(qū)的價格歧視程度并不一致,這與我國郵電通信行業(yè)在各地區(qū)的發(fā)展的非均衡性相一致。第二、通過對電信套餐資費的分析發(fā)現(xiàn),東部地區(qū)和西部地區(qū)資費的價格歧視程度較大,而中部地區(qū)和東北地區(qū)的價格歧視較小。第三、基于郵電通信行業(yè)各省的價格歧視,本文用空間模型對其進行研究,發(fā)現(xiàn)我國各省郵電通信行業(yè)價格歧視存在顯著且逐漸增強的空間正相關性。這說明通信行業(yè)的價格歧視受到鄰接區(qū)域定價的影響。局部空間相關性方面,通信行業(yè)整體表現(xiàn)為高-高分布,和低-低分布兩種空間格局。但電信行業(yè)的熱點集中于東部地區(qū),冷點集中于西部地區(qū),而郵政行業(yè)則相反。第四、在研究各省郵電通信行業(yè)價格歧視和人均收入關系時,本文發(fā)現(xiàn)用空間滯后模型和空間誤差模型進行計量更為適合,且價格歧視和人均收入存在正相關性。同時本文還發(fā)現(xiàn)隨著市場勢力的增強,郵電通信行業(yè)的價格歧視程度增大。
[Abstract]:The competition mechanism introduced by the post and telecommunications industry has formed the pattern of monopoly competition at present. On the one hand, the price control of the post and telecommunications industry is gradually loosening. On the other hand operators through price discrimination to achieve more benefits. Previous studies mostly from a qualitative point of view to explore the telecommunications industry price discrimination and its impact has not directly measured price discrimination. At the same time, space measurement is not introduced into the measurement of price discrimination in post and telecommunications industry. This paper completes the following four tasks: first, the fixed effect model is used to measure the price discrimination in the postal and telecommunications industry in China, and the movement situation is analyzed. Second, the price discrimination of the package fare in the telecommunications industry is analyzed. In order to prove the correctness of the model to measure price discrimination. Third, the introduction of spatial measurement model, the study of the postal and telecommunications industry price discrimination spatial layout. Finally. This paper analyzes the relationship between price discrimination, per capita income and market power in post and telecommunications industry. The results are as follows: first, according to the fixed effect model, the price discrimination value of post and telecommunications industry is calculated, and it is found that the degree of price discrimination in the communication industry as a whole and telecommunications industry has weakened year by year. At the same time, the degree of price discrimination in the post and telecommunications industry is not consistent, which is consistent with the unbalanced development of the postal and telecommunications industry in various regions. Through the analysis of the telecom package price, it is found that the price discrimination in the eastern and western regions is greater, while the price discrimination in the central and northeast regions is relatively small. Third. Based on the price discrimination in various provinces of the post and telecommunications industry, this paper uses the spatial model to study it. It is found that there is a significant and increasing spatial positive correlation between the price discrimination of posts and telecommunications industry in each province of China, which indicates that the price discrimination in the communication industry is affected by the adjacent region pricing. The overall performance of the communication industry is high-high distribution and low-low distribution. However, the hot spots of telecommunication industry are concentrated in the eastern region, the cold point is concentrated in the western region, and the postal industry is opposite. 4th. In the study of the relationship between price discrimination and per capita income in the postal and telecommunications industry in various provinces, this paper finds that the spatial lag model and spatial error model are more suitable for measurement. And there is a positive correlation between price discrimination and per capita income. At the same time, it is found that with the increase of market power, the degree of price discrimination in post and telecommunications industry increases.
