判断平台是否完成了可持续转型,可以通过一组剪刀差指标观察:一端是单位交易变现率的变化,另一端是供给侧的满意度指标,例如留存率或净推荐值。如果变现率持续上升,而供给侧满意度同步下滑,这种赚钱方式本质上仍是竭泽而渔。只有当两者同时改善,平台的转型才具备长期稳定性。

Unai Emery has seen most things in this game but he has never won at Wolves. In three and a half years at Villa, he has lost two and drawn one of his three games at Molineux. Twelve months ago they lost this fixture 2-0 and this week Emery shared his poor record to stress the difficulty of the challenge facing his side, particularly given they have won just one of their past five matches in all competitions. Emery even mentioned his visit to Wolverhampton with Arsenal in 2019, when his team trailed 3-0 at half-time and lost 3-1. For Emery, there is no better time to break his duck, with the schedule dictating that Villa could move nine points clear of fifth-placed Chelsea, who visit Villa on Wednesday, before Liam Rosenior’s side travel to Arsenal on Sunday. Victory would enhance Villa’s chances of returning to the Champions League but also pile pressure on direct rivals. Ben Fisher
