本研究主要探討企業的網路搜尋量與分析師提供投資建議報告之關聯，考慮到企業網路搜尋量與分析師提供投資建議報告之關聯，考慮到企業網路搜尋量與分析師提供投資建議報告之關聯，考慮到企業財報公布日前的網路搜尋量提高，代表投資人對該企業關注升促使市場財報公布日前的網路搜尋量提高，代表投資人對該企業關注升促使市場財報公布日前的網路搜尋量提高，代表投資人對該企業關注升促使市場財報公布日前的網路搜尋量提高，代表投資人對該企業關注升促使市場財報公布日前的網路搜尋量提高，代表投資人對該企業關注升促使市場業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故業的討論更加熱絡，進而吸引分析師目光增對於企之報告提供意願故以網路搜尋量出發，討論分析師投資建議報告與企業以網路搜尋量出發，討論分析師投資建議報告與企業以網路搜尋量出發，討論分析師投資建議報告與企業盈餘宣告日前後的網路搜尋量之關聯性，驗證關聯性，驗證關聯性，驗證企業盈餘宣告日前網路搜尋量的變化，是否會增加分析師提供報告之意願，是否會增加分析師提供報告之意願，是否會增加分析師提供報告之意願再探討企業盈餘宣告日前網路搜尋量的變化，是否加強日前網路搜尋量的變化，是否加強日前網路搜尋量的變化，是否加強分析師投資建議報告量與投資人對該企業的網路搜尋量之正向影響。實證結果顯示，實證結果顯示，企業盈餘宣告日前之網路搜尋熱度和分析師提供之投資建議報告量不存在顯著的正相關，另外企業盈餘宣日前網路搜分析師提供之投資建議報告量不存在顯著的正相關，另外企業盈餘宣日前網路搜分析師提供之投資建議報告量不存在顯著的正相關，另外企業盈餘宣日前網路搜分析師提供之投資建議報告量不存在顯著的正相關，另外企業盈餘宣日前網路搜分析師提供之投資建議報告量不存在顯著的正相關，另外企業盈餘宣日前網路搜尋量提高，對分析師投資建議報告尋量提高，對分析師投資建議報告尋量提高，對分析師投資建議報告和與投資人對該企業的網路搜尋量沒有顯著有顯著正相關，且分析師投資評等的不一致性與人對該企業網路搜尋量同樣沒有顯著且分析師投資評等的不一致性與人對該企業網路搜尋量同樣沒有顯著且分析師投資評等的不一致性與人對該企業網路搜尋量同樣沒有顯著且分析師投資評等的不一致性與人對該企業網路搜尋量同樣沒有顯著正向影響。

摘要(英)

The present study primarily investigates the association between a company′s online search volume and the provision of investment recommendation reports by analysts.Considering the increased online search volume prior to a company′s financial statement release,which signifies heightened investor interest and greater market discussions about the company,analysts are more likely to pay attention and provide analysis reports on the company.Thus,starting from the perspective of online search volume,the study explores the relationship between the volume of analyst investment recommendation reports and the changes in online search volume before and after the company′s earnings announcement. It examines whether the fluctuations in online search volume prior to the earnings announcement strengthen the willingness of analysts to provide reports and whether they enhance the positive impact of analyst recommendation reports on investor online search volume.The empirical results indicate that there is no significant positive correlation between online search intensity prior to the earnings announcement and the volume of analyst investment recommendation reports.Additionally,the increase in online search volume prior to the earnings announcement does not significantly moderate the relationship between analyst recommendation reports and investor online search volume. Moreover,the inconsistency of analyst investment ratings does not significantly moderate the relationship between investor online search volume and the volume of analyst recommendation reports.
