以“宽带中国”战略作为准自然实验,利用2011—2020年284个地级市层面的数据实证分析了数字基础设施建设对新建企业选址的影响,结果显示,数字基础设施建设能够吸引新建企业选址,且随着时间推移,影响效应越来越大;数字基础设施建设对新建企业选址存在异质性影响,数字基础设施建设更能够吸引新建企业在东部、南方以及南部沿海、北部沿海、东部沿海、长江中游、东北五大经济综合区选址;更能够促进新建企业在距离中心城市0~250公里范围内的周边城市选址,而对中心城市或偏远城市则没有影响;更能够吸引服务业企业选址,其次是生活性服务业,而对制造业行业影响最小。数字基础设施建设对新建企业选址的影响主要通过成本降低效应、创新水平提升效应的机制发挥作用。

从关于说谎者悖论的“句方程”方案中可以提炼出总的看法:说谎者悖论是语言学中一种相当纯粹的代数学现象。这是“句方程”方案的必然结论。实际上,“句方程”方案全面吸收了代数学的思想成果,从基本定义开始,就是参照代数学的思想建立和展开的。而之所以可以把说谎者悖论与代数学做如此深度的连接,根本原因在于三卡悖论的发现。三卡悖论是说谎者悖论与布尔代数深度相关的无可辩驳的证据,是“句方程”方案立论的基础。
