【摘要】：邮电通信行业引入的竞争机制形成了目前垄断竞争的格局,一方面邮电通信行业价格管制逐渐放松,另一方面运营商通过价格歧视来实现更多的利益。前人的研究大多从定性的角度探讨通信业价格歧视及其造成的影响,尚未直接测度价格歧视,同时也未将空间计量引入邮电通信行业价格歧视的测度中。本文完成以下四项工作:其一,采用固定效应模型来测量中国邮电通信行业的价格歧视,并分析其运动态势。其二,分析电信行业套餐资费的价格歧视,以此来佐证上述模型计量价格歧视的正确性。第三,引入空间计量模型,研究邮电通信行业价格歧视的空间布局。最后,分析邮电通信行业价格歧视和人均收入以及市场势力的内在关系。研究结果如下:第一、根据固定效应模型,计量得出分地区邮电通信行业价格歧视数值,发现通信行业整体和电信行业的价格歧视程度逐年减弱,而邮政行业的价格歧视有增强趋势。同时,邮电通信行业各地区的价格歧视程度并不一致,这与我国邮电通信行业在各地区的发展的非均衡性相一致。第二、通过对电信套餐资费的分析发现,东部地区和西部地区资费的价格歧视程度较大,而中部地区和东北地区的价格歧视较小。第三、基于邮电通信行业各省的价格歧视,本文用空间模型对其进行研究,发现我国各省邮电通信行业价格歧视存在显著且逐渐增强的空间正相关性。这说明通信行业的价格歧视受到邻接区域定价的影响。局部空间相关性方面,通信行业整体表现为高-高分布,和低-低分布两种空间格局。但电信行业的热点集中于东部地区,冷点集中于西部地区,而邮政行业则相反。第四、在研究各省邮电通信行业价格歧视和人均收入关系时,本文发现用空间滞后模型和空间误差模型进行计量更为适合,且价格歧视和人均收入存在正相关性。同时本文还发现随着市场势力的增强,邮电通信行业的价格歧视程度增大。
[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.
