experiments, and presenting research results in the form of data.4 It is based on mathematical logic,
probability theory and the principle of statistics. By constructing models, developing hypotheses and
quantifying the collected data, ELS aims to analyse legal practices in a given social context.5 Judicial
precedents and the conduct of judges were the initial subjects of ELS.6 For example, Louis Brandeis,
who was a judge on the Supreme Court of the United States in the early twentieth century, reviewed a
large number of labour-related cases prior to concluding that long working hours would affect workers’
health, and the research ndings inuenced subsequent judicial decisions.7
This feature of being able to extract information and draw conclusions from a large number of past
cases has helped ELS especially gain prominence in the countries with case law legal tradition.8 Empirical
studies of different cases provide a basis for penalties and justifications that are deployed by judges,
lawyers and other justice professionals. With the advent of digital revolution, the possibility of building
models for automatic retrieval of provisions or cases was explored. Many courts and law firms in the
common law system started to retrieve and upload a large number of case materials to online bases,
which facilitated the research endeavours of legal scholars and practitioners.9 Consequently, the number
of articles with an empirical focus in law journals increased dramatically. Legislators and policymakers
also use ELS to investigate the operation effect of the current judicial system and predict the trend of
future policies. One example is using ELS to inform judicial reform, especially to investigate the rate of
case closure and misjudged cases.10 The methodology of empirical analysis is increasingly being applied
to various scenarios in the field of legal research and practice. Accordingly, many elite law schools have
attempted to introduce lectures and programmes on empirical research.11
The Development of ELS in China and Chinese Legal Scholars’ Views on ELS
Interest in empirical studies in China is similar to developments in other countries, that is, it began in
sociology, especially within the subeld of criminology.12 For example, the Chinese sociologist and

10 For instance, the European Commission for the Efficiency of Justice was established in 2002. The Commission examines the
quality of judges’ trials and the effectiveness of judicial operation in different judicial systems through quantitative analysis, using
standardized indicators, questionnaires and field research. As a result of this evaluation and data generated, the caseload allocation
mechanism of courts and judges was optimized. See Council of Europe, Evaluation of Judicial Systems, Eur. Com. for tHE

11 For example, the Harvard Empirical Legal Studies (HELS) Series explores a range of empirical methods, both qualitative and
quantitative, and their application in legal scholarship in different areas of the law. It is a platform for engaging with current
empirical research, hearing from leading scholars working in a variety of fields, and developing ideas and empirical projects. See
