在一篇关于并购的论文里读到这样一段关于国企收购者(目标公司)和私企收购者(目标公司)话:
“
At firm level, we choose ownership types of target and acquiring firms as key predictors. SOE target and SOE acquirer, respectively, indicate whether the two partners in the transaction are state-owned enterprise (code as 1) or not (0). Private target and Private acquirer, respectively, indicate whether the two partners in the transaction are private (code as 1) or not (0)”
不是很明白这个1和0是怎么设置的。如果按照我的理解是如果收购公司和被收购公司都是SOE,那么虚拟变量设为1,都不是设为0。或者都是私企,设为1,都不是设为0。这种设定感觉怪怪的。而且Logit回归结果如下:
 
不理解为什么SOE acquirer,SOE target,Private acquirer,Private target前面的系数和显著性都是怎么来的?之前不是成对设定的么?附上论文,请教一下各位大牛。
