1. Introduction
Temperature change and environmental issues have become important issues affecting global economic and social development, and they have attracted widespread attention. To address this issue, the Chinese government made active commitments at the UN General Assembly to achieve a carbon peak by the year 2030 and carbon neutrality by the year 2060. With enterprise as the micro foundation for the development of a green economy, Chinese regulators require companies to incorporate environmental protection into their corporate governance systems. As a response to the dual carbon goal and promoting corporate sustainable development, the number of Chinese firms that release ESG reports has increased rapidly [
1]. The rapid development of ESG in practice has aroused increased discussion; existing studies have discussed how to promote the development of enterprise ESG from the institutional and firm level [

3,
4,
5], but little attention has been paid to whether analysts can impact corporate ESG performance, thus ignoring the possible influence of analysts, who are important participants in capital markets. In this paper, we focused on whether analysts are a crucial external governance mechanism that can influence corporate ESG performance.
There are incentives for analysts to consider corporate ESG performance [
6]. The demand for ESG information from stakeholders, especially investors, drives analysts to focus on corporate ESG performance. In recent years, investors have realized that “climate risk is investment risk”, and the development of a low-carbon economy will make some assets depreciate rapidly or even become liabilities [
7]. This has pushed investors to shift to a sustainable development investment strategy. Therefore, more and more investors are taking corporate ESG performance into consideration when making investment decisions, which leads to exponentially increasing demand for corporate ESG information. Investors’ demand for firms’ ESG information has forced analysts to shift more attention to understanding corporate ESG performance. Corporate ESG information not only provides non-financial information, but also contains a useful supplement to the firm’s financial information, which helps analysts to better understand a company’s fundamentals, form more accurate estimates of a company’s value, and improves the analyst’s forecast quality [

10]. Analysts also have the ability to influence corporate ESG performance. Analysts can alleviate the information asymmetry between the capital market and corporate management. By releasing their interpretation of the enterprise ESG report, analysts increase external investors’ understandings of the real situation of corporate ESG. Analysts are a significant external corporate governance force, who can effectively detect corporate misconduct and discipline management behaviors by playing a moderating role. For example, analyst coverage reduces firms’ pollution and improves their corporate ESG performance.
To date, there has been no serious investigation into the impact of analyst coverage on corporate ESG performance. To bridge this knowledge gap, in this paper, we focused on the role of the analyst in influencing corporate sustainable development, in particular, corporate environmental, social, and governance (ESG) performance. Using data from Chinese A-share listed firms from 2011 to 2021, we investigated the relationship between analyst coverage and corporate ESG performance. Our results showed that analyst coverage improves corporate ESG performance, especially the environment (E) and social (S) dimensions, proving that analyst coverage is an important driving force promoting corporate ESG engagement. The promotion effects of analyst coverage on corporate ESG are more significant for state-owned firms and firms facing greater financial constraints and high information asymmetry. Attracting media attention and participating in site visits are the two potential channels through which analyst coverage improves corporate ESG performance. The results remained valid after a series of endogeneity and robustness checks, including the instrumental variable, Heckman two-stages method, entropy balance matching, alternative variable measures, and change samples.
Our research contributes to the literature in the following ways: first, our study enriches the research on corporate ESG performance driving factors. Regarding the determinants of firm ESG performance factors, prior studies were predominantly conducted at the country-level and firm-level, based on institutional and legitimacy theories [
11,
12], such as policy regulation [
2], investors [
5,
13], board structure [
1], and managerial characteristics [
4,
14,
15]. The influence of the analyst, an important participant in capital markets, has been largely ignored. In this study, we focused on analyst coverage as an external driving factor affecting corporate ESG performance. Furthermore, in contrast to developed countries with formal regulations and mature market environments, the ESG development of Chinese enterprises is still in its infancy. It is of significance to explore the impact factors of corporate ESG in China using Chinese A-share listed firm data. Our research provides evidence from emerging markets for ESG-related research.
Most of the prior studies of analyst coverage have focused on examining the influence on a firm’s capital markets and the economic consequences [
16,
17]. This may ignore the impact of analyst attention on corporate non-financial information. With the widespread development of ESG around the world, and the demand from investors for corporate ESG information, analysts are increasingly required to provide the actual conditions of corporate ESG. Analysts are also paying more attention to a firm’s non-financial information; our research provides evidence that analysts have an influence on corporate non-financial performance from the perspective of firm ESG performance.
The influence of analysts on corporate decisions is controversial. By focusing on the information role and monitoring role of the analyst, we offer an analytical framework that explains the complex relationship between analyst coverage and corporate ESG performance. Because of the imperfect formal system, Chinese listed firms are often plagued by serious agency problems [
18]. Our results prove that analysts discipline management behavior through improving information transparency, by playing an information provision role, and increasing the likelihood of violations being detected through a monitoring role. Our study confirmed that analyst coverage is an important external monitoring mechanism, and may make a marginal contribution to agency theory.
Lastly, we have added to the literature on analyst coverage and firms’ sustainable development. Existing studies have reported that analyst coverage increases corporate philanthropy [
19], improves workplace safety and increases employee welfare via a supervisory role [
20], and shapes corporate environment policies by increasing the cost of a firm’s environmental misbehaviors [
21]. These studies proved that analyst coverage is a driving force in promoting corporate sustainable development, but they focused on analyst coverage within a specific dimension of ESG; there remains a lack of direct tests of how analyst coverage affects firm sustainability development under the overall framework of corporate ESG. Regarding analyst influence on firm sustainability development, we explored the impact of analyst coverage on corporate ESG performance and bridged the knowledge gap in this relationship. Our research provides strong evidence within the broader literature by providing theoretical insights into the underlying mechanisms by which analyst coverage may affect corporate sustainability.
The remainder of this paper is structured as follows.
Section 2 presents the literature review on corporate ESG and hypothesis development;

Section 6 gives the conclusions and implications.
6. Conclusions and Implications
6.1. Main Conclusions
As the micro foundation for the development of a sustainability economy, in order to achieve the Chinese government’s commitment of the “dual-carbon goal” and to promote energy conservation and emission reduction, firms are encouraged to engage in ESG activities. With the vigorous development of ESG, much research has emerged to explore the determinants of corporate ESG performance. In this paper, we examined how a third-party information intermediary—an analysts—can affect firms’ sustainable development under the ESG framework.
We used Chinese A-share listed firms from 2011 to 2021 as a sample and Bloomberg ESG rating scores as a measurement of corporate ESG performance to explore the relationship between analyst coverage and corporate ESG performance. Our main conclusions were as follows: analyst coverage improves corporate total ESG performance, proving that analyst coverage is an important driving force behind corporate ESG engagement. Analyst coverage mainly promotes the performance of the environmental (E) and social (S) dimensions, and has a less obvious impact on the governance dimension. A possible reason for this is that, in our sample, the score of the corporate G pillar was much higher than that of the E pillar and S pillar; therefore, the improvement effect of analysts was not obvious. In additional tests, we first tested the heterogeneity of corporate characteristics, and found that analyst coverage mainly improves non-state-owned firms’ ESG performance, because non-state-owned firms are more market-oriented and pay more attention to market responses. Analyst coverage improves the corporate ESG performance among firms with higher financial constraints by facilitating external financing opportunities and reducing financing costs; this effect is more significant among firms with low information transparency, mainly because analyst coverage reduces the information asymmetry between insiders and outsiders. Furthermore, we examined the potential channels through which analyst coverage improves corporate ESG performance, and found that attracting media attention and participating in site visits are two channels by which analyst coverage improves corporate ESG performance. Our results remained valid after a series of endogeneity and robustness checks, including using the instrumental variable, Heckman two-stages method, entropy balance matching, alternative variable measures, and change samples.
6.2. Implications
Our research highlighted the role analysts play in corporate non-financial performance from the perspective of enterprise ESG performance, enriching research on the effect of analyst coverage on corporate governance. Our findings have the following implications:
- (1)
The role analysts play in corporate governance should be fully valued. Analyst attention to corporate non-financial information should not be ignored, and although analyst coverage may put pressure on management, our findings proved that analyst coverage plays a positive role in promoting firms’ sustainability development in an emerging markets scenario.
- (2)
Firms should pay attention to and improve their ESG performance by establishing a sound ESG framework and making more investments in ESG activities, thereby promoting their sustainable development. Furthermore, good information transparency provides an opportunity for outsiders to understand the real ESG performance of enterprises. Companies should increase the degree of ESG information disclosure to the authoritative ESG framework and show details of the real ESG performance of the company to outsiders.
- (3)
For investors, the non-financial information of an enterprise also has value and contains information. Investors should take the ESG performance of enterprises into account when selecting investment targets. This can not only reduce investment risks and increase investment return, but can also promote the sustainable development of society.
- (4)
From the perspective of regulators, policy makers should create favorable policies and laws for ESG construction in firms, and encourage firms to actively participate in ESG development within the formal system. First, regulated policy should consider firms’ property rights and financing constraints, use market incentives to guide non-state-owned enterprises to participate in ESG construction, and carry out financing reform and expand financing channels for enterprises to address the difficulty and high cost of financing for non-state-owned enterprises. Regulators should have a rational view of the role analysts play in influencing the development of corporate ESG as an informal institution, strengthen the supervision of analysts, and guide analysts to participate more effectively in corporate governance.
6.3. Limitations and Future Research
Although our study complements existing research on the driving factors of corporate ESG performance, and may have potential implications for other developing markets, there are limitations to consider. First, this study was based on Chinese A-share listed firms, and although the number of Chinese firms publishing corporate ESG reports is growing rapidly, Chinese corporate ESG is still in its infancy, and it is still a minority of firms that publish well-developed corporate ESG reports. Due to limited data availability, the generalizability of the conclusions of this paper to mature markets remains to be tested. Future research could explore the relationship between analysts and corporate ESG performance in diverse contexts.
Second, following the existing literature [
32], this paper used the annual number of analysts as a proxy variable to measure analyst coverage. This is a common measurement of analyst coverage; however, it ignores the possible impact of analyst heterogeneity. In this paper, we focused on the relationship between analyst coverage and corporate ESG performance and the potential firm-level characteristics that may influence this relationship, and did not address the possible impact of analyst characteristics on this relationship. Therefore, future research could consider the impact of the heterogeneity of analysts, such as career focus, effort allocation, and expertise, on corporate ESG performance.
Finally, we studied the impact of analyst coverage on the three dimensions of corporate ESG performance, and explored the possible channels by which analysts affect the overall ESG performance of firms. However, we did not distinguish whether there are different impact mechanisms of analyst coverage on the three dimensions of corporate ESG performance. Future research could further explore the different potential mechanisms by which analyst coverage affects these three dimensions.
