Efficiency evaluation and optimization of rural ecotourism space based on DEA model

Since the reform and opening up, with the development of China's economy, the demand for tourism has been increased. The traditional agriculture has not been able to satisfy the diversified consumption demand; as a result, the rural ecotourism develops rapidly. Based on such a situation, the data envelopment analysis (DEA) model was used in this study; the relevant data of Guangxi province such as the number of star hotels and number of tourists were referred to. The efficiency of rural ecotourism space was calculated. According to evaluation analysis of spatial dynamic efficiency, it could be found that although the comprehensive technical efficiency of the southeast coastal areas was lower than 1, it was still higher than other regions. The pure technical efficiency ofmany regions was equal to 1, and the scale benefits were increasing. Regions with moderate political and economic levels had high pure technical efficiency and maintained above the national level, but they were relatively small in scale and needed to increase input indicators. However, the comprehensive technical efficiency of relatively backward areas in northwest China was relatively low, which remained at about 0.3. Therefore, more investment and government support are needed to expand the scale.
