摘要

本研究使用2009年美国数字有线电视系统的横断面数据库，考察垂直整合和区域集中(有线电视集群)对有线电视网络的运输和层定位的综合影响。这项研究集中在四个基本的有线电视网络部分——户外、卡通、电影和康卡斯特附属网络——发现垂直整合通过增加有线电视用户对综合网络的访问而减少了他们对非附属网络的访问，从而降低了有线电视用户的节目可用性。报告还发现，无论垂直所有权如何，电缆系统区域集中度的增加对总体基本电缆网络的可用性都有积极影响。区域集中度的增加也与垂直整合效应的减弱有关，表明区域集中度带来的系统效率可能会缓解垂直整合效应。

Vertical Integration, Regional Concentration, and Availability in Cable Programming Networks

Using a 2009 cross-sectional database of digital cable systems in the United States, this study examines the combined effects of vertical integration and regional concentration (cable TV clusters) on the carriage and tier positioning of cable networks. Focusing on four basic cable network segments—the outdoor, cartoon, movie, and Comcast affiliated networks—this study finds that vertical integration has reduced program availability for cable subscribers by increasing their access to integrated networks and by limiting their access to unaffiliated networks. It also finds that an increase in the regional concentration of cable systems positively affects the availability of overall basic cable networks, regardless of vertical ownership. An increase in regional concentration is also associated with a decrease in the effects of vertical integration, suggesting that system efficiency through regional concentration may mitigate the vertical integration effect.

期刊介绍： The Journal of Media Economics publishes original research on the economics and policy of mediated communication, focusing on firms, markets, and institutions. Reflecting the increasing diversity of analytical approaches employed in economics and recognizing that policies promoting social and political objectives may have significant economic impacts on media, the Journal encourages submissions reflecting the insights of diverse disciplinary perspectives and research methodologies, both empirical and theoretical.
