摘要
当人力资本存在差异时,贸易开放对居民收入差距会产生不同影响。本文的实证研究发现只有当人力资本高于门槛值时,贸易开放才能缩小居民收入差距;而当人力资本低于门槛值时,贸易开放则会扩大居民收入差距。这是因为只有当人力资本存量较高时,贸易开放引致的技术进步效应才能使较多劳动者受益,从而达到缩小居民收入差距的效果;而当人力资本存量较小时,影响效果则恰好相反。分区域样本的实证检验也在一定程度上验证了本文的结论。
When there is a difference of human capital,trade openness will have a different effect on residential income gap.In this paper,with empirical analysis,I find that as long as the human capital is higher than threshold value,trade openness can narrow the residents＇ income gap.While the human capital is lower than threshold value,trade openness will broaden the income gap.It is because as long as human capital stock is higher,technological advance effect caused by trade openness can do benefit on more workers,and then narrow the income gap.When the human capital stock is smaller,the effect is different.And the empirical test of sub-regional sample can also testify the conclusion in a degree.
