The measurement of productive performance with consideration for allocative efficiency

This data set includes the primary sources of costs and revenue for a sample of 37 Japanese securities companies observed over the years 2011-2015. The data were gathered from annual securities report as published by each securities company. Those annual reports can be found from the investor relations library of each company’s homepage or Japan Securities Dealers Association (JSDA). The sample size is the 14.6% of members in JSDA (as of the end of the fiscal year 2016, the number of Japanese securities members in JSDA totaled 253 companies, excluding foreign securities members). According to JSDA, we further separated those observed companies into four groups. Note that M1~M5 are the major securities companies, B6~B12 are the bank-affiliated securities companies, O13~O19 are the online brokers, and I20~I37 are the other integrated securities companies.

本数据集涵盖了2011-2015年间观测的37家日本证券公司的成本与收入主要来源。相关数据采集自各证券公司发布的年度证券报告，这些年报可从各公司官网的投资者关系资料库，或是日本证券业协会（Japan Securities Dealers Association，JSDA）获取。本次样本占日本证券业协会会员总数的14.6%：截至2016财年末，日本证券业协会的日本籍证券会员总计253家，不含外国证券会员。依据日本证券业协会的分类规则，本次观测的样本企业被进一步划分为四组：M1~M5为大型证券公司，B6~B12为银行附属证券公司，O13~O19为在线经纪商，I20~I37为其他综合证券公司。
