Due to low industrial land prices and inefficiently used industrial land, China’s central government has reformed land regulations in order to promote more market-oriented industrial land. Considering the differences in land management between developed and developing countries, this study aims to investigate the impact of land use regulations on industrial land prices in China and the effect of market-oriented reforms of industrial land policy. Measures that capture multiple dimensions of land use regulation tools are incorporated into OLS models based on a micro dataset from 1999 to 2016 that covers Jiaxing City in Eastern China. The results show that (1) The land policy implemented in 2006 to promote industrial land marketization has had a very limited effect; (2) The impact of land supply on industrial land prices was decreased for land transferred through listings after 2006, which implies an immature marketization; (3) Zoning instruments has obvious effects on industrial land prices; (4) The results imply that the effect of land use regulations varies with firm ownership and development zones. The findings in this paper clearly show that the industrial land market should be more open and competitive and combined with a rational land supply to promote the market-oriented price mechanism.

To systematically evaluate the safety and efficacy of high-intensity interval training in children and adolescents. Rationale: Eight databases were searched. Descriptive analysis of the efficacy and safety of high-intensity interval training on body shape, cardiorespiratory fitness, and metabolic risk markers for cardiovascular disease between children and adolescents.

Objective To systematically evaluate the safety and efficacy of high-intensity interval training in children and adolescents. Methods Eight databases were searched. Descriptive analysis of the efficacy and safety of high-intensity interval training on body shape, cardiorespiratory fitness, and metabolic risk markers of cardiovascular disease in children and adolescents. Subgroup analysis was performed using age, participants, intervention time, and exercise frequency as covariates. Results 47 studies included 2995 children and adolescents. The results of the meta-analysis showed that high-intensity interval training significantly improved cardiorespiratory fitness indicators (VO2max, SBP, DBP and HRmax) and cardiovascular disease biomarkers (TC and HDL-C). HIIT had no significant effect on body shape indicators (BMI, BF% and WC) or cardiovascular disease biomarkers (TG and LDL-C). Conclusion Currently, there is insufficient evidence that HIIT with interval running as the predominant form improves physical indicators in children and adolescents. However, HIIT can be promoted in children and adolescents to improve cardiorespiratory fitness and reduce some metabolic risk of cardiovascular disease.

Land marketization and its effects are widely documented across developing countries. Few studies, however, have investigated the link between industrial land price determination and industrial land market reform, based on the establishment of a pilot open trading platform for the secondary market. Moreover, no studies have specifically examined the link between primary and secondary industrial land markets. This study, therefore, investigates industrial land price determination using a quasi-natural experiment to interpret distortions in industrial land prices in China. Using industrial land sales data for 2006–2017 in the city of Haining, Zhejiang Province, China, this study compares industrial land value in the secondary market with land transfer prices in the primary market and identify undervaluation in the primary market. The results show that the growth rate of industrial land transfer prices increased every year after the open trading platform was established. Moreover, compared with nonpilot districts and counties, industrial land prices in the pilot city (Haining) increased by 11.14% from 2015 to 2017. The findings suggest that, based on the pilot program, further market reforms should be undertaken by establishing open trading platforms in a broader area.

Objective: To systematically evaluate the safety and efficacy of high-intensity interval training in children and adolescents. Design: Systematic Review and Meta-Analysis. Methods: Eight databases were searched. Descriptive analysis of the efficacy and safety of high-intensity interval training on body shape, cardiorespiratory fitness, and metabolic risk markers for cardiovascular disease between children and adolescents. Subgroup analysis was performed with age, participants, intervention time, and exercise frequency as covariates. Results: 47 studies included 2995 children and adolescents. Meta-analysis results showed that high-intensity interval training significantly improved cardiorespiratory fitness indicators (VO2max, SBP, DBP and HRmax) and cardiovascular disease metabolic risk indicators (TC, HDL-C). HIIT had no significant effect on body shape indicators (BMI, BF% and WC) and some cardiometabolic indicators (TG and LDL-C). Conclusion: Current evidence shows insufficient evidence that high-intensity interval training with intermittent running as the main form of exercise improves body shape indicators in children and adolescents. Nevertheless, it deserves to recommend for the purpose of improving cardiorespiratory fitness and reducing the metabolic risk of cardiovascular disease.
