The purpose of this article is to investigate the role of securities analysts in Chinese stock market. Taking the earnings announcements of listed companies, analysts' earnings forecast and analysts' recommendations in Chinese stock markets from 2014 to 2018 as the samples, this paper explores the influence mechanism of investor sentiment on the market reaction to announcements, and investigates the influence mechanism of investor sentiment on the role of securities analysts under the framework of behavioral finance theory. On the basis of theoretical analysis, this paper empirically tests the relationship between the information content of analysts' reports and the information content of the earnings announcements from the perspective of behavioral finance, and discusses the role of securities analysts in the stock market. The results show that during the periods of high investor sentiment, securities analysts do not demonstrate the role of information competition or information supplement. On the other hand, during the periods of low investor sentiment, securities analysts play the role of information competition or information supplement. Furthermore, after excluding the investor sentiment component of the market reaction to announcements, securities analysts do not demonstrate the role of information competition, but play the role of information supplement. The findings of this study offer new insights into the role securities analysts play in Chinese stock market, which is conducive to improving the quality of analysts' reports, thus enhancing the efficiency of the securities market.

AbstractResource depletion and environmental pollution have seriously restricted the sustainable development of China's economy in recent years. How to transform the extensive growth mode to the intensive growth mode and realize the green development of economy is a great challenge for China. In this paper, we use the non‐radial and non‐angle Slack‐based Model (SBM) considering the undesired output, combined with the Malmquist–Luenberger productivity index, to measure regional green total factor productivity (GTFP). By constructing the green output density function, the theoretical model of the relationship between regional GTFP and industrial agglomeration is deduced, and the theoretical mechanism of the influence of industrial agglomeration on regional GTFP is analyzed. Based on panel data of 243 cities at the prefecture level in China from 2010 to 2019, this article employs the dynamic spatial panel model to empirically estimate the impact of industrial agglomeration on regional GTFP. The empirical results show that regional GTFP shows significant spatial autocorrelation and spatial clustering characteristics. The manufacturing agglomeration has significant negative impact on regional GTFP and produces negative spatial spillover effect on the surrounding regions, but does not produce congestion effect. The producer services agglomeration significantly improves regional GTFP and produces positive spatial spillover effect on the surrounding regions, and leads to congestion effect. The co‐agglomeration of producer services and manufacturing has significantly promoted the improvement of regional GTFP and produces positive spatial spillover effect on the surrounding regions. Finally, this article puts forward policy suggestions on how to promote regional GTFP and achieve green development from the perspective of industrial agglomeration.
