But the broader outlook for networking sites is more encouraging. One reason is that advertisers are being drawn to the leading sites by their sheer scale. Facebook's audience is bigger than any TV network that has ever existed on the face of the earth. Another thing that has attracted companies is the networks' ability to target ads with laser-like precision, thanks to the data they hold on their users' ages, gender, interests and so forth. Although there are still lingering concerns about brands appearing next to racy content, firms seem more willing to run this risk now that the networks' advertising proposition has become more compelling.
In addition to advertising-driven business model, networks are already making healthy profits from sales of games and virtual goods. The beauty of this business for social networks is that the cost of producing and storing virtual inventory is minimal. Moreover, because these are closed markets, networks can fix prices at levels that generate fat margins. To some, the notion that big money can be made from selling make-believe items may seem bizarre. But the practice replicates the physical presents that people give to one another to cement relationships in the real world.

我们应该积极促进结构性改革，特别是供给侧改革。中国经济发展面临结构性的矛盾，供给和需求两侧都有，主要在供给侧，我们要用改革的办法推进结构调整，减少无效和低端的供给，扩大有效和中高端的供给，这既有利于经济转型，也有利于促进经济增长。
其中重要的方面就是要淘汰严重过剩的产能，重点是抓好钢铁、煤炭等困难行业去产能，近年来已经取得些许成就，生煤和生铁产量下降，但还要进一步减少，主要是运用市场化和法治化手段，严格环保、质量、安全等标准。去产能最大的难题是人往哪里去。企业要采取多种措施使职工转岗不下岗，中央和地方政府都要对职工分流安置给予必要的支持。产能过剩是一个全球性的问题，我们将主动采取行动去产能，这本身就表明中国是负责任的大国。
