The airline operation control center is the core of the airline, and the flight dispatcher is the core of the operation control center, so the efficiency of the operation control center has a direct impact on the operation safety and efficiency of the airline. Based on the characteristics and management status of airline flight dispatcher, the efficiency quantification and efficiency evaluation are analyzed and studied, and an evaluation model suitable for the operation efficiency of airline flight dispatcher in China is established by adopting the method of combination of analytic hierarchy process(AHP) and matter-element extension model. Aiming at the evaluation index more targeted and operable under the actual situation, 4 criteria and 16 indexes are proposed and analyzed with example, which are based on the evaluation index system of the operation efficiency of the dispatcher. The results show that, the evaluation Index system is reasonable and effective, which can truly reflect the close relationship between the operating efficiency of the airline and the flight dispatcher, transportation and control equipment, airlines operation center(AOC) organization structure and working environment and airline management regulations, and put forward the theoretical basis for the improvement of the operating efficiency of the company.

The purpose of this study is to examine the effects of government subsidies and private research and development (R&D) on global value chains position (GVCP) and the moderating role of task complexity in China. It utilizes regional data from official Chinese statistics and the Trade in Value Added 2018 database from the period of 2005–2016. The results indicate that different sources of R&D funds have different effects on GVCP. In particular, government subsidies promote GVCP, while private R&D impedes GVCP. Furthermore, the results indicate that task complexity positively moderates the relationship between private R&D and GVCP, and it negatively moderates the relationship between government subsidies and GVCP. Therefore, this study highlights the importance of task complexity for regional enterprises seeking to enhance their GVCP and provides policymakers with new insights into their subsidy policies.

Combined with the global value chain (GVC) and the innovation value chain, this study analyses whether and how global value chain participation (GVCPA) and global value chain position (GVCPO) affect innovation efficiency (IE) to explain the difference of IE in China's provinces from 2005 to 2016. It uses Stochastic Frontier Analysis to examine the influencing factors of IE. Results show that both GVCPA and GVCPO are important factors influencing IE, with GVCPA promoting IE and GVCPO inhibiting IE. Moreover, human capital (HC) positively affects the relationship between GVCPO and commercialisation efficiency as well as the relationship between GVCPA and R&D efficiency. The findings suggest that a region should not only encourage industrial enterprises to be embedded in the GVC but also develop education and improve the quality of HC. [ABSTRACT FROM AUTHOR]
