Unlike rural migrants heading for industrial jobs, it will be much more difficult to guide educated and creative professionals using the hukou system. The boom in the successful cities, therefore, will hollow out human capital from less attractive industrial hubs, which will then fall into a vicious cycle of decay and falling productivity.
与此同时，那些后工业时代的宠儿，比如上海和北京，将吸引更多更聪明且教育程度更高的产业工人后代前来。跟农村移民不同，这些创造性专业人士更加难以用户口制度来管理。因此这些成功城市的兴起将挖空那些弱势工业城市的人力资本，而后者将随之陷入衰败和生产力下降的死循环之中。
