本研究探讨了有线电视系统的多样化，分为三个非传统的服务：按次付费电视，高速互联网接入和电话。基于产业组织模型的计量经济学模型，探讨了导致电缆系统之间的多样化变化的因素。具体而言，本研究探讨三组变量，即有线电视系统的特点，市场结构和市场人口统计，影响有线电视系统多元化。进行多元线性回归，以确定有线电视系统的总的多样化程度，这是定义为从0到3，由有线电视系统提供的三个非传统服务的数量的决定因素。回归结果表明，多系统运营商（MSO）的所有权，基本有线电视服务用户的数量，和广播电视台的数量可接收的空中都有一个统计上显着的正关系，有线电视系统的总多样化程度，而数字高-在有线电视特许经营地区的高速互联网服务提供商与有线电视系统的总多样化程度有统计学上显着的负相关关系。
This study examines cable system diversification into three nontraditional services: pay-per-view television, high-speed Internet access, and telephony. An econometrics model based on the Industrial Organization Model is used to explore the factors that have led to variation in diversification among cable systems. Specifically, this study examines how three sets of variables, namely, cable system characteristics, market structure, and market demographics, influenced cable system diversification. Multiple linear regression was performed to identify the determinants of cable system total degree of diversification, which is defined to be the number, from 0 to 3, of the three nontraditional services offered by a cable system. Regression results indicate that Multiple System Operator (MSO) ownership, the number of basic cable service subscribers, and the number of broadcast television stations receivable over the air all had a statistically significant positive relationship to cable system total degree of diversification, whereas the number high-speed Internet service providers in a cable franchise area had a statistically significant negative relationship to cable system's total degree of diversification.
