困难,首先是对于文章的理解和把握,比小组作业时要求更高,而一篇文章的重点和难点有很大部分在于理论推演的过程中,它是读懂文章的关键,因此读懂一篇论文的摘要、文献回顾、研究设计思想是极其重要的。在复制论文之前,多花点时间一定要将作者的研究思路弄明白,这样才能有助于在实际操作过程中的顺利进行,才能达到真正意义上的节约时间。
8.3 实证技能体会
实证过程整个流程实际上就是理论分析的产物,由理论分析得出的研究设计思路做指导。实证过程中取得数据是第一步,在取得数据之前应该先将模型弄明白,整理出整个研究过程都需要哪些变量,而不是遇到需要的数据就去下载一次,这样思路更加清晰,效率更快。
对于模型的理解主要用于实证过程操作,对各种软件SPSS和STATA应用能力的要求随之提高,实证过程中软件的应用能力也是影响工作效率的一大因素。在这次复制论文过程中,我运用软件的能力明显比上学期有所提高,能够进行一些思考,而不是仅仅按照套路来做,还会分析一下某一步的原理之类。运用ACCESS进行匹配的时候,也更加熟练,效率也更高,并且意识到了ACCESS某些操作步骤的不可逆转性,因此及时保留了数据,没有出现重新来过等现象。
8.4如何克服工作难点
此次论文复制过程遇到的困难多是理解文章研究设计思路和筛选处理数据阶段,对三个会计稳健性指标认识的不够充分,因而在计算稳健性指标时遇到了比较大的障碍,不理解指标的得出过程,对STATA的应用还是不太熟练,因此花费了很多时间,通过和同学商量找到了解决办法。将样本数据进行配比是一项很费时间的工作,技术含量不高,但是过程繁琐,容易出错,这部分数据处理占用了比较多的时间。
还有在之前并未学习很多计量模型,对于模型的理解和把握有一定的困难,还有统计上某些系数检验之类,都不知道它们代表着什么意义,我通过上网查阅相关资料以及与其他同学讨论,自学了相关理论知识,了解到各种统计方法各自的适用范围,并且探索出来怎样用SPSS操作。这种自学方式虽然遇到比较多困难,可是能让自己学到很多,也能加强相关理论知识的学习,熟练掌握各种数据库和统计软件的应用。
