社会资本可能在社会距离与COVID-19患病率之间起中介作用
Social capital may mediate the relationship between social distance and COVID-19 prevalence
摘要：
新型冠状病毒（COVID-19）的威胁正在增加。关于各地区感染率的差异，除了寻找社会距离（人口密度）差异原因的研究外，寻找社会资本差异原因的研究也有增加的趋势。然而，关于社会资本即使控制了人口密度的影响，是否也会影响感染率的研究尚未进行。因此，本文使用各都道府县的统计数据，分析了感染率、人口密度和社会资本之间的关系。统计分析表明，社会资本不仅与感染率和人口密度相关，而且在控制人口密度影响的情况下与感染率仍呈负相关。此外，以平均年龄控制变量间的关系，发现社会资本与感染率的相关性大于人口密度。换句话说，社会资本在人口密度和感染率之间起着中介作用。这意味着单靠社交距离不足以阻止冠状病毒感染，还需要为社会资本充电。
英文摘要：
The threat of the new coronavirus (COVID-19) is increasing. Regarding the difference in the infection rate observed in each region, in addition to studies seeking the cause due to differences in the social distance (population density), there is an increasing trend toward studies seeking the cause due to differences in social capital. However, studies have not yet been conducted on whether social capital could influence the infection rate even if it controls the effect of population density. Therefore, in this paper, we analyzed the relationship between infection rate, population density, and social capital using statistical data for each prefecture. Statistical analysis showed that social capital not only correlates with infection rates and population densities but still has a negative correlation with infection rates controlling for the effects of population density. Besides, controlling the relationship between variables by mean age showed that social capital had a greater correlation with infection rate than population density. In other words, social capital mediates the correlation between population density and infection rates. This means that social distance alone is not enough to deter coronavirus infection, and social capital needs to be recharged.
