    Grant number：17K17731

    Grant amount：\3640000 （ Direct Cost: \2800000 、 Indirect Cost：\840000 ）

    In this study, we obtained many results regarding the optimization of Internet advertisement distribution. The main achievements are the following three points. First, we proposed a classification model for websites based on LDA. Second, we proposed a method for measuring the effectiveness of Internet advertising based on a state-space model. Third, we proposed a factor analysis method for the effectiveness of Internet advertising based on ensemble learning. In addition to these major achievements, we applied the knowledge gained from research on Internet advertising to mobile coupons and obtained useful suggestions for optimizing mobile coupon distribution.

    4 2016 - 3 2022

    Grant number：16K03805

    Grant amount：\4420000 （ Direct Cost: \3400000 、 Indirect Cost：\1020000 ）

    This research focused on organizational capabilities at the sales outlet level through quantitative analysis of Japanese automobile dealers. In keeping with expectations from the literature, sales capabilities (which allow for an organization to respond to the needs of a region), marketing capabilities (which allow an organization to understand and differentiate its products), and leadership by the head of a sales outlet were found to have an effect on sales performance. The research found findings suggest that effective leadership will be different for a top salesperson and other salespeople. Interestingly and counterintuitively, behavior-controlling leadership was found to be more effective for top salesperson, while autonomy-enhancing leadership was found to be more effective for other salespersons. The research results suggests way for Japanese companies to improve their white-collar productivity, which has been found to be rather low in international comparative studies.

    Grant number：18H00882

    Grant amount：\14690000 （ Direct Cost: \11300000 、 Indirect Cost：\3390000 ）

    Speculating possible strategy and organization to utilize bigdata and SNS technology is quite urgent issue for business organization and academics. We provided two directions in the research of such hyper-flexible business organization. In one direction we focus on clarifying mechanism of aligned flow of material and information. And in the other direction, we aimed at ever changing demand process and tried to take it into the business process.
    We got the following result. We developed gaming methodology for the analysis of corporate strategy that allows us dynamic if-then conditions, especially in servitization of manufacturers. As to marketing strategy, we designed and implemented a mechanism that allows us to use SNS in usual commerce. A wide variety of questionnaire-based research on supply chain management are conducted, and we showed some important relationship among flexibility, quality management, and others.

    本年度は,市場反応の時間依存性について,大別して2つの研究を行った.
    1つ目は,最寄り品カテゴリーにおける市場反応の時間的な変化のメカニズムを実証的に明らかにした研究である.本研究では,市場反応の変化は,長期的な傾向の変化と異質な消費者の混合割合に起因する一時的な変化によるものと仮定し,状態空間モデルの枠組みを用いて,市場反応係数が時間と共に変化するブランド選択モデルを構築した.3年間のインスタント・コーヒーのスキャナ・パネル・データを用いた実証分析の結果,ブランド固有の魅力度はほとんど変動がないことや,プロモーションの効果は時間と共に変化するが,特別陳列とチラシでは,効果の変動の仕方に違いがあることなどが確認された.
    2つ目は,インターネット広告のクリック率の予測に関する研究である.インターネット広告に対する期待が高まるにつれ,その効果の予測および適切な効果測定を行うための手法が求められてきている.本研究では,状態空間モデルをベースに,バナー広告のクリック率を予測するモデルを構築し,実際の広告配信データを用いて実証分析を行った.分析の結果,本研究のモデルは,将来のクリック率を十分な精度で予測でき,かつ,クリック率の長期的な傾向の変化や曜日によって異なる特徴をとらえることができた.この分野の研究はまだ始まったばかりであり,インターネット広告の技術の進歩と共に今後ますます注目されることが予想される.
