#### 6.1.1 Number of Science and Technology Personnel (N_SRTSP)  
During the six-year study period, the minimum value of the GWR regression coefficient of N_SRTSP was negative, while the maximum value was positive (Table 2). These results indicate that the N_SRTSP's inferiority had significant spatial differentiation.  
In Figure 5, the regression coefficients of N_SRTSP show apparent spatial heterogeneity and regularity in the 2012-2017 period. Specifically, in 2012, N_SRTSP and inferiority gradually changed from a positive to a negative correlation from north to south in China. The regions with the strongest positive correlation were mainly concentrated in northeast, north, and central China and in parts of the Yangtze River Delta, while the negative correlations were mainly concentrated in parts of northwest China. From 2013 to 2014, the

(All of the variables are the number of people from different groups, specifically, N_SRTSP: Science and technology personnel; N_AP: Agriculture practitioner; N_MP: Manufacturing practitioner; N_CoP: Construction practitioner; N_CaP: Catering practitioner; NS_RIME: Students in regular institutions of higher education; NS_VSS: Students in vocational secondary schools; NS_RSS: Students in regular secondary schools).  
negatively correlated areas were mainly located in parts of northeast and northwest China, and the negatively correlated areas nationwide decreased significantly. By 2017, inferiority and N_SRTSP showed a significant positive correlation in most of the areas in China.  
A possible reason for these variations is that in 2015, China proposed the \"double world-class project\" to build several world-class universities and disciplines by the end of 2050 [46]. In the following years, universities and academic institutions (especially those in

economically developed areas) accelerated the introduction of talent and significantly increased the assessment requirements for scientific researchers (especially young researchers who had just begun to work in the field) [29]. These excessive assessment requirements led to a dramatic increase in the amount of pressure on the scientific researchers. According to previous studies, excessive pressure can easily lead to inferiority [47; 48]. On the other hand, for individual researchers, those who have not yet achieved results often feel inferior when other researchers who have been brought in during the same period have done so.  
Therefore, the government and relevant departments need to take appropriate measures. On the one hand, they should guide universities and scientific research institutions to formulate policies and assessment mechanisms for the introduction of talent that are in line with their actual conditions to prevent excessive pressure, which can lead to inferiority [36; 37; 49]. On the other hand, steps should be taken to encourage scientific researchers to pay attention to the work-rest balance and take care of their mental health [14; 15]. Finally, the government should increase their investment in the health and medical industry, actively improve local health and medical service facilities, and develop health and medical services [50; 51]. Moreover, psychological counseling centers should be established in schools, communities, and other densely populated areas, and the informatization level of counseling should be actively improved to enhance people's access to psychological support.
