3.1.1 Comparison of per capita annual income of Beijing municipality-level specialized public health institutions
Comparing the annual income of workers in specialized public health institutions of Beijing municipal level and average wage level of the health industry in Beijing between the years 2011 and 2016. We find that wage levels in the Municipal Health Supervision Institute (HSI) (45,000 ~ 95,000 yuan), and the Municipal Tuberculosis Control Institute (TCI) (80,000 ~ 120,000 yuan) are noticeably lower than the wage level of the overall health industry average (85,000 ~ 160,000 yuan). The gap is especially noticeable for the Municipal HSI. The average per capita income of the Centre for Disease Control and Prevention (CDC ) (90,000 ~ 130,000 yuan), the Municipal Emergency Medical Centre(EMC) (90,000 ~ 160,000yuan ) and the Red Cross Blood Centre (RCBC) (100,000 ~ 155,000 yuan) was close to the average level of the health industry in Beijing, but the income of the Municipal CDC in 2016 declined markedly. In contrast, the wage levels of the Municipal Maternal and Child Health Care Institution (MCHCI) (135,000 ~ 250,000 yuan) and Municipal Mental Health Institution (MHI) (90,000 ~ 190,000 yuan) were higher than the average level of the health industry in Beijing (Fig. 1).
3.1.2 Annual income change for middle and upper professional of specialized public health institutions at Beijing municipal level
In the municipal MHI the annual income of staff holding professional position was at a high level among Beijing municipal-level specialized public health institutions between 2011 and 2016. The average annual income of senior professional positions is 50,000 ~ 80,000 yuan. In second place are the Municipal Emergency Medical Centre and Red Cross Blood Centre. In 2016, the annual income of staff above middle and upper professional was more than 200,000 yuan. The Municipal HSI, Municipal CDC, and Municipal TCI still give low salaries, and the senior professional positions have no significant wage difference compared with the average annual income (Fig. 2) of the overall workforce.
3.2 Changes of per capita annual income of specialized public health institutions at district level in Beijing
3.2.1 Comparison of per capita annual income in specialized public health institutions and in the overall health industry at district level in Beijing
Looking at the annual income of Beijing’s district specialized public health institutions (Fig. 3), we see that the income of staff in various institutions has improved in recent years. The average annual growth rate is 8%~16%, and the income level of all district level agencies is roughly similar. In 2016, the per capita annual income of the health sector at district level in Beijing was about 120,000 yuan. Comparing the annual income of district level public health institutions to the average wage level in the municipal health sector between the year of 2011 and 2016, we found that were all lower than the average wage level of the city's health sector (85,000 ~ 160,000 yuan). The income of the district level CDC (70,000 ~ 120,000), the district HSI (75,000 ~ 130,000), the district MCHCI (75,000 ~ 135,000 yuan), the district MHI (55,000 ~ 115,000 yuan), the district TCI (60,000 ~ 105,000 yuan), and the Blood Collecting and Supplying Agencies (BCSA) (75,000 ~ 120,000 yuan). The gaps are obvious.
3.2.2 Annual income change for middle and upper professional of specialized public health institutions at district level in Beijing
In the average annual income of staffs above the middle and upper professional level in specialized public health institutions at district level in Beijing, the income levels in the Blood Collecting and Supplying Agencies (BCSA) and Mental Health Institutions (MHI) are somewhat higher. The income levels of Health Supervision Institutes, CDC and Tuberculosis Control Institutes are roughly similar to each other, but are somewhat lower than the former (Fig. 4).
3.3 The trend of average annual income change of community health service staff in different functional areas of Beijing
The annual per capita income of staff in the Beijing Community Health Service Institutions (including community health service centres and community health service stations) increased gradually between 2011 and 2016. In 2011, the annual per capita income was 52,800 yuan, which increased to 88,900 yuan in 2016. The average annual growth rate was 10.98%.
There are four functional areas including the capital core function areas, the city new function expansion area, the urban development new area and the ecological conservation area in Beijing[7]. As far as different functional areas are concerned, the annual income of personnel in various district community health service institutions also showed an incremental trend. Among them, the average annual income of staff in the capital core function areas was somewhat higher, and the growth rate was somewhat greater The average annual growth rate was 14.43%, hence the annual income of the personnel in 2016 reached 107,100 yuan. In the city new function expansion area, 他the average annual income of staff increased from 52,300 yuan in 2011 up to 90,300 yuan in 2016 with an average annual growth rate of 11.55%.
