同时，过去分析中国经济增长动因的时候，一个流行的表述是地方政府之间的“GDP竞赛”极大刺激了经济增长。而这次疫情防控中初现端倪的地方之间的公共治理竞争，如果能持续深化，其意义绝不下于地方政府之间的GDP竞争。

Mainly Macro: Comment on macroeconomic issues
This evidence suggests two important but provocative conclusions, which for me represent tentative hypotheses rather than anything firm. First, the key division in UK society today as far as elections are concerned is the social liberal/conservative divide, rather than ABCD class divisions or how left wing economic policy is.[2] Brexit was not an aberration but part of a trend. The big divide in the UK is partly age but mainly education. [3] The political right understands this, which is why elections will be fought on proxies for this divide. …

中国是一个口罩产业大国，生产了全球约50%的口罩。在疫情发生之前，中国口罩最高日产为2000多万只。数据显示，2015-2019年中国大陆地区口罩产业产值增长率在10%以上。2019年，中国大陆地区口罩产量超过50亿只，产值高达102.35亿元。最快的口罩生产速度120-200只/秒，但一个解析消毒的标准流程却需要7天到半个月。因为医用口罩采用环氧乙烷灭菌，灭菌后，口罩上会有环氧乙烷残留，不但刺激呼吸道，还有致癌物。这样一来，就必须通过解析方式，使残留的环氧乙烷释放，达到安全含量标准，经检测合格后，才能出厂上市。下图为普通及医疗口罩生产厂家分布图。
