In recent years, earnings management, as a hotspot in financial accounting research, has received widespread attention from Chinese and foreign scholars. In response to this problem, Chinese and foreign scholars have conducted empirical research in various aspects, and have made some research results worthy of attention. However, although some research results of empirical accounting scholars on earnings management objectively reveal some regular phenomena in this field, so far no consensus has been reached on issues of general significance. There are many different opinions on the concept of earnings management in the accounting field, and they can be divided into two categories. The first is that American accountant William R. Scott argued in his “Financial Accounting Theory” that earnings management means that, within the scope permitted by GAAP, the choice of accounting policies enables the operator’s own interests or the enterprise The act of maximizing market value. On the other hand, Katherine Schipper, an American accountant, believes that earnings management is actually a “disclosure management” in which corporate managers purposefully control the external financial reporting process to obtain certain private benefits.
Accounting information is the cornerstone of the operation of the capital market. With the gradual development of China’s capital market, the quality of accounting information has also received increasing attention from investors and regulatory authorities. Especially after the introduction of equity incentives, because management compensation is closely related to company performance, it often controls earnings for personal benefits, reducing the authenticity of accounting information, which not only affects the long-term development of the enterprise, but also causes economic losses to investors. In order to ensure the stability of the capital market, the academia and the physical world have always paid enough attention to the issue of earnings management. Therefore, this article will review the academic research results of 6 top journals on earnings management in China from 2015 to 2019. Firstly, I will sort out the relevant literature and classify the article according to the research theme. Secondly, I can find out the current factors affecting earnings management and the possible economic consequences of earnings management and the role of earnings management as an impact path through analysis while exploring the development of earnings management issues in China. Finally, this article discusses the development trend of China’s earnings management issues and puts forward constructive opinions on China’s future earnings management research.

Xu et al. (2017) found that CEO used earnings management to hide bad news in their tenure and the last year before their departure. It was founded by Lin et al.

3. Sample Selection and Classification
This article selects six domestic top academic journals in the field of economic management. These six journals are Economic Research, Management World, Accounting Research, Financial Research, China Industrial Economy, World Economy. Articles published in these six journals can basically represent the latest domestic economic management research fields and mainstream research directions, and it can be said that it has a guiding role in the research of economic management. After selecting these six journals, this article uses the five years from 2015 to 2019 as the selection period of the journal. Read each article one by one, and classify the topic of the article according to the influencing factors of earnings management, the economic consequences of earnings management, and earnings management as the impact path. If the article cannot be included in the above classification, it is classified as other. Based on this, there are 77 related articles on the research about earnings management were obtained in 6 journals. The relevant data comes from the China Knowledge Network Research Database.
4.1. Descriptive Statistics
It can be seen from Table 1 that in the past 5 years, a total number of 77 articles on earnings management during the five years in China while the literature on earnings management has been published every year. But the number of related literatures is still relatively large. In addition, although the total amount of literature on earnings management during the past five years has decreased, the overall trend is relatively stable. It is worth noting that the literature on earnings management in the past five years has mainly focused on the journal of accounting research, mainly because earnings management is a focus in the accounting field, which also shows that the problem of earnings management research in the domestic accounting community has become very common This is both a research focus and a research hotspot.
By studying the literature on earnings management in 6 mainstream journals in China, this paper classifies the literature on earnings management in four aspects. The classification results are shown in Table 2. The first is the factors that affect earnings management, the second is the economic consequences of earnings management, the second is the study of earnings management as an impact path, and the last is the literature that studies earnings management in these six journals but cannot be classified into the above three categories.
4.2. Research Methods
Among the total number of 77 Chinese literatures on earnings management retrieved, empirical research methods occupy an absolute dominant position in these studies on corporate earnings management. In these documents, the empirical models selected are generally multivariate linear logistic regression models, multiple logarithmic linear regression models, multiple linear regression models, and double difference models. Among them, the multiple linear logarithmic regression model and multiple logarithmic linear regression model are mostly used, which is also the model that is used more in the academic research of accounting. Generally, the number of independent variables and control variables involved in the model is relatively large. Generally, they are common control variables, and the analysis is also clear.
Table 1. 2015-2019 earnings management literature statistics.
Table 2. Statistical of research perspectives on earnings management literature.
By analyzing the relevant literature on domestic earnings management, it can be seen from the above analysis that the literature on earnings management is mainly focused on the factors affecting earnings management, accounting for 69% of the literature on earnings management in the five years from 2015 to 2019. The second one is the economic impact caused by the research of earnings management and earnings management, and the literature that cannot be classified into the above three categories. The entry point and perspective of the factors that affect earnings management are also extensive. These studies indicate that the current related research is no longer limited to the study of the impact on earnings management from the perspective of internal systems, executive behavior and background, but will cut in from novel perspectives such as macro policies and environmental protection and text tone. The research on corporate earnings management behaviors has provided a broad space for research on earnings management. In addition, there are relatively few studies on the economic consequences of earnings management and earnings management as an impact path. In the future, we can focus on these two aspects.
