Under the green high-quality development, technological innovation brings technological advance which is a critical drive for human capital to lead industrial structure adjustment. This paper, based on 2005 to 2020 panel data of China’s 30 provinces, establishes a mediating effect regression model with technological advance as mediating variable, which is employed to study the whole region and each single region. Innovative human capital can improve industrial structural upgrading through technological progress. Each region needs to improve its industrial structural layout through increasing educational and technological investment to improve innovative human capital quality and quantity and then push industrial structural upgrading. Industrial structural adjustment requires a higher quality and quantity in human capital in more developed areas. Innovative human capital can largely promote technological advances in the whole region, but more in the underdeveloped areas where there are less technological advancing effects. Innovative new human capital can promote a rationalized development of industrial structure in the whole region by means of complete mediating effect, but unfavorable for industrial upgrading. In developed regions where there is better self-innovative capacity, a higher requirement of self-innovation on innovative human capital will weaken the indirect effect of innovative human capital on industrial structural adjustment, and intensify the direct effect, showing an indirect effect of innovative human capital on industrial structure by masking effect. In less-developed regions, innovative human capital has an indirect effect on industrial structure through the mediating effect of technological advance, mainly from understanding, adopting and copying imported technologies with lower indirect effect. Driven by the Western Development Strategy, innovative human capital can directly impact industrial structural upgrading in underdeveloped regions. The potential impacting mechanism of innovative human capital on industrial structural upgrading includes investing rate which obviously plays a positive adjusting role in the eastern and western regions. Except in the western region, financing level plays a strikingly positive adjusting role while innovative human capital impacts industrial structural upgrading. Innovative human capital impacts industrial structural rationalization positively in the whole region. This paper presents suggestions on boosting education of innovative human capital, establishing regional talent cultivating system, improving self-innovative capacity and optimizing industrial environment.

Urban mining refer to the recyclable secondary resource, its stock is significant to mitigate resource pressure and promote circular economy. This paper uses an up-to-down way to calculate the in-use stock of copper, iron and aluminum in Fujian province during 1978 to 2016. The stocks of copper, iron and aluminum had increased by 10, 15 and 22 times, respectively, equivalent to 2.4, 290, and 7.4 million tons. In 2016, average stock per person of copper, iron and aluminum is 58kg, 7.6t and 191kg, far below the developed nations. Their sources indicate that infrastructure contribute to copper stock at most, up to 62%, most from electronic lines, construction contribute to iron and aluminum up to 80% and 40%, most from residence constructions. This research also sets up a long term stock database of copper, iron and aluminum for Fujian province, which is used to analyze their stock size, increment mode, category and department. This paper provides data support for Fujian to develop and use urban mining, and offers references for provincial or city management of copper, iron and aluminum resources.
