| In recent years,inbound tourism in coastal provinces has shown a rapid development momentum,occupying an important position in the national inbound tourism market.At present,inbound tourism in China’s coastal provinces has developed to a certain scale,and efficiency has become the key to measuring the quality of tourism economic growth,so China’s inbound tourism should accelerate the transition from pursuing growth in quantity to emphasising growth in quality.At the same time,due to the differences in tourism resources and economic levels of coastal provinces,their inbound tourism development history and characteristics are different,and the spatial differences in the efficiency of inbound tourism in coastal provinces reflect the uneven development of inbound tourism,which has become a hot spot of academic attention at present.Firstly,this paper analyses the theoretical mechanism of inbound tourism efficiency and its influencing factors,combining input-output theory,economic efficiency theory,sustainable development theory and economic growth stage theory,and finds that tourism efficiency is influenced by tourism resources,scientific and technological innovation,economic coordination,ecological civilisation,openness to the outside world and shared development.Secondly,this paper uses the data envelopment analysis method to quantify the inbound tourism efficiency of coastal provinces from the input-output perspective,and uses the natural break method in geostatistics and global spatial autocorrelation analysis to compare the differences in the spatial distribution of inbound tourism efficiency of coastal provinces in different regions.Finally,according to the connotation of high-quality development of tourism economy,this paper constructs an index system of influencing factors of inbound efficiency from the perspective of new development concept,and carries out regression through Tobit model to identify the specific factors affecting inbound tourism efficiency and puts forward countermeasure suggestions in a targeted manner.The main findings are as follows:(1)In terms of spatial differences in efficiency,coastal provinces in the Pan-Pearl River Delta region have a high level of efficiency,with Guangdong ranking first among the 11 provinces in terms of overall efficiency;coastal provinces in the Yangtze River Delta region have an intermediate level of efficiency,with Shanghai ranking second only to Guangdong Province in terms of overall efficiency;coastal provinces in the Bohai Sea Rim region have an overall low level of efficiency,with Hebei and Shandong provinces ranking at the bottom of coastal provinces in terms of overall efficiency for a long time.(2)In terms of the time-series changes in efficiency,the efficiency of inbound tourism in the last 16 years in five provinces,namely Hebei,Liaoning,Jiangsu,Guangxi and Tianjin,has been increasing on the whole,while the efficiency of inbound tourism in the remaining provinces has shown a decreasing trend year by year,mainly due to the negative impact of insufficient technical management level.(3)In terms of the factors influencing efficiency,tourism resources,the level of tourism information technology and urban environmental conditions have the most significant impact on inbound tourism efficiency,while the level of marine economic development,marine ecological conditions and the level of foreign capital utilisation have a smaller impact on inbound tourism efficiency.Based on the above analysis,this paper proposes countermeasures to optimise the allocation of existing resources,increase investment in information technology research and development,actively cultivate high-end tourism talents,strengthen cooperation and exchange between coastal provinces in different regions,improve urban and marine environmental conditions and create an international tourism brand image. |
