摘　　要：伴随着电视技术的发展,数字电视替代模拟电视是一种必然趋势,数字电视在我国发展迎来快速发展的机遇,同时也面临诸多挑战。文章利用联立方程模型分析影响数字电视转换的制约因素,结果显示:在整体转换策略下,有线数字电视转换取得的成就是显著的,但是转换后收视率和收视时间反而呈下降趋势,这是由于我国有线电视产业缺乏有效竞争导致的;有线数字电视的转换与模拟电视的普及率显著正相关,模拟电视的收视率对数字电视的转换影响大于模拟频道数量,互联网普及率的提高、模拟电视频道数量的增加不利于有线数字电视的转换,人均居民收入对有线数字电视转换的影响并不显著。With the development of TV technology,it is an inevitable trend that digital TV replaces analogue TV.Digital TV has the opportunity of rapid development in China,but it also faces many challenges.In this paper,simultaneous equation model is used to analyze the restriction factors of digital TV conversion.The results show that under the overall conversion strategy,the achievement of CATV conversion is significant,but after the conversion,the audience rating and viewing time are declining,which is caused by the lack of effective competition in China’s CATV industry.There is a significant positive correlation between the conversion of cable digital TV and the penetration of analog TV.The impacts of analog TV ratings on digital TV conversion is greater than the number of analog channel.The increase of Internet penetration and the number of analog TV channels is unfavorable to the conversion of cable digital TV.The effect of per capita resident income on the conversion of cable digital TV is not significant.
