Dynamic Pricingとは?
Dynamic pricing( surge pricingなどとも呼ばれる)は現在の市場での需要に応じて
柔軟に設定価格を変える価格戦略のこと。需要と供給の関係、競合の価格付けなど
を織り込んでいる。
野球におけるDynamic Pricing
順位や需要(曖昧!)によってチケットの価格を変える。

やってみる
データ
内容:
・NPBの公式サイト(http://npb.jp/)
- 観客動員数
- 勝敗、順位、貯金など
・天気
- 平均気温
など
データ
対象:(とりあえず面倒くさいさわりなので)
- 2017年シーズン
- パリーグのみ(順位変動)
- ホームゲームだけみる(オリックスがほっともっとと京セラDになるので省略)
- 対戦カードは交流戦をベースに計算
分析手法
とりあえず回帰分析
順位、前日勝ったかどうか、デーゲームかナイターか、天気、最高気温、
曜日(火曜基準)、月、対戦相手
価格をやりたい。でも・・・
オークションでの価格を取りたい。
→ヤフオク!
いつの試合かカテゴリだけだとわからない。一個一個見る場合名寄せが辛すぎ。
→チケ◯◯◯
過去分遡れない、というか 1サイトは今停止している。
なので前段階として需要がどのような要因で動いているかを見る。
ソフトバンク
・順位 +
・祝日、金土日 +
・デーゲーム +
・雨(ドームなので開催できるが客足が遠のく?)
・対西武 +
西武
・祝日デーゲーム+
・祝日 +
・晴れ +
・気温 -
・日曜 +
楽天
・土日 +
・ソフトバンク +
日本ハム
・月曜 、木曜 -
・デーゲーム +
ロッテ
・順位(下がると増える?なんでや・・)
・5,6月 -
・月曜 -
・楽天 -
課題
・1シーズンしか見ていないのでサンプルサイズ小さい。
・どういう状況での勝ちかで分けたりしていない。
・ローテとか特定の投手が先発かをみたい。
・などなど
