Data for: 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2011至2015年间观测的37家日本证券公司的成本与收入主要来源。数据源自各证券公司公开披露的年度证券报告，此类报告可从各公司官网的投资者关系资料库，或日本证券业协会（Japan Securities Dealers Association，JSDA）获取。本次样本量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共计253家，不含外国证券会员）。按照日本证券业协会的分类标准，本次观测的企业被进一步划分为四组：其中M1~M5为大型证券公司，B6~B12为银行关联证券公司，O13~O19为在线经纪商，I20~I37为其他综合类证券公司。
