“…Successful marketing strategies require companies to manage relationship between organizations and shape corporate boundaries (Chatterji et al , 2018); focus on the use of social media and use competitive intelligence, engagement and word of mouth to adjust the relationship between sales strategy and sales performance in a timely manner (Pham and Johnson, 2017); focus on the impact of cultural and social impacts on sales strategies (Micu et al , 2017); incentive salespeople through natural reward strategies (Singh et al , 2018), offer different commissions to salespeople for new products and remanufactured products and so on Kovach et al (2017); ensure that salespeople do not accept unrealistic and unsurpassed expectations from consumers (Rodriguez et al , 2018). It can be seen from the above that scholars mainly start from the external environment (Pham and Johnson, 2017), social environment (Micu et al , 2017), inter-organizational relationship (Chatterji et al , 2018), internal salesperson (Kovach et al , 2017; Singh et al , 2018) and consumers (Rodriguez et al , 2018). They used sentiment analysis (Micu et al , 2017), questionnaires (Singh et al , 2018; Pham and Johnson, 2017), text document analysis (Rodriguez et al , 2018) and other methods to study marketing strategies.…”
