An empirical study on the influence of digital empowerment of China's tea industry on the quality of tea export——Empirical analysis based on 25 tea export provinces
Based on the data of 25 major tea export provinces in China from 2005 to 2021,this paper uses a two-way fixed effect model to empirically analyze the impact of the digitalization level of China's tea industry on the quality of tea export at the provincial level.By constructing a comprehensive index of digital empowerment of the tea industry,the paper calculates the level of digital empowerment of the tea industry in China and 25 provinces by using the entropy method,and carries out heterogeneity analysis according to the origin of tea exports and more subdivided types of tea.The research results show that the digital empowerment of the tea industry in each province has a significant role in promoting the quality of tea exports in each province,and the level of digital empowerment of the tea industry in each province increases by 1%,The quality of tea exports from all provinces will increase by 1.3448%.The coefficient of R&D investment(RD)is negative,but it is significant at the statistical level of 1%.The R&D investment cannot promote the current tea export quality.The coefficient of production cost(ppi)is negative,significant at the statistical level of 1%,showing a negative correlation.The coefficient of labor force(human)is positive and significant at the statistical level of 1%.Farmers'enthusiasm for tea is improved and attention is paid to the quality of tea.The coefficient of open trade is positive,and it is significant at the statistical level of 10%,indicating that with the improvement of the openness of foreign trade in each province,the understanding of tea consumption demand in export destinations will promote the improvement of tea export quality.The coefficient of education quality(edu)is positive,which indicates that the expenditure on education of each province will cultivate high-quality talents,thus promoting the quality of tea export.From the perspective of tea-producing and non-tea-producing provinces,the digital enabling level of tea industry in China's tea-producing provinces has a significant impact on the quality of tea export in the province at the statistical level of 1%,that is,every 1%increase in the digital enabling level of tea industry in the tea-producing provinces will increase the quality of tea export by 1.3912%;The level of digital empowerment of tea industry in non-tea producing provinces can also promote the quality of their tea exports at the provincial level,which is significant at the statistical level of 5%.From the perspective of tea segmentation,the digital empowerment of the provincial tea industry has a more significant role in promoting the export quality of black tea,followed by green tea,followed by scented tea and Pu'er tea,and has no significant impact on oolong tea.Therefore,the higher the digital empowerment of the tea industry,the more it can promote the improvement of the quality of China's tea export,and the digital empowerment of the tea industry not only enables the tea trade link but also enables the tea production link,thus improving the quality level of tea export.
