Firstly, this paper analyzes the present situation and development trend of supply-side reform at home and abroad. Based on the situation of Xi’an, the author analyzes ？ ve production-side reforms, such as “de-production,” “de-stocking,” “deleveraging”, “cost reduction” The author puts forward the main problems of Xi’an’s supply-side reform to promote economic growth. Finally, it puts forward the path choice of supply-side reform to promote economic growth in Xi’an.

The new phase Pm-3m of InS under high pressure is firstly reported in the work. The structural features and electronic structure under high pressure of InS are fully investigated. We predicted the stable ground-state structure of InS was the Pnnm phase and phase transformation of InS from Pnnm phase to Pm-3m phase is firstly found at the pressure of about 29.5 GPa. According to the calculated enthalpies of InS with four structures in the pressure range from 20 GPa to 45 GPa, we find the C2/m phase is a metastable phase. The calculated band gap value of about 2.08 eV for fnS with Pnnm structure at 0 GPa agrees well with the experimental value. Moreover, the electronic structure suggests that the C2/m and Pm-3m phase are metallic phases.展开更多
