B选项，怎么知道持续经常账户赤字4%才是不好的呢？

B国的人均收入一直在下降，这是一个潜在的政治压力来源。B是错误的，因为持续的经常账户赤字一直低于G的2%。持续的经常账户赤字超过G的4%，这可能意味着缺乏竞争力。C是不正确的，因为B国一直在向国际财务报告准则过渡，预计在两年内完全趋同，这是更好的会计准则的积极发展。 1、A为啥是politics讲义关于politicrisk（willingness to pay），只提到了以下4点，也没提高人均G吧。另外人均G下降，我理解属于ability to pay，应该属于economic risk吧，怎么就属于politicrisk（willingness to pay），更多是还款能力而不是还款意愿吧· 较弱的产权法（property right）、较弱的合同法实施主权豁免（sovereign immunity），即投资他国资产不受到本国法律保护（legrisk）· 财产充公，公司国有化，腐败（politicrisk）· 两党多政府引发政治不稳定性（politicrisk）· 资本管制，限制货币转换（没有将外币换回本币的渠道）（politicrisk）2、另外关于B看讲义应该是economic risk吧（经常账户赤字/G小于4%），答案解析为啥是competitive
