Low operation voltage, large resistance ratio and good uniformity were achieved in W/VO2/Pt selection device. The selector is applied to Ti/HfO2/Pt RRAM device, forming 1S1R configuration, to reduce the sneak path current. Ti/HfO2/Pt crosspoint array size can be improved from 8×8 to 128×128 by introducing the W/VO2/Pt selection device from readout margin simulation. Additionally, the selector can be used in sub-10nm scale RRAM to suppress sneak leakage current.

From the perspective of industrial structure advancement and rationalization, this paper studied the impact of regional industrial structure upgrading on the economic growth of marine fisheries through theoretical analysis and empirical tests. The results show the effects of different industrial structure upgrading on the economic growth of marine fisheries is varied. The advancement evolution has a “suppression effect,” while rationalization evolution has a “promotion effect.” The adverse impact of advancement evolution is greater than the favorable impact of rationalization evolution. Therefore, the development of marine fisheries reduces this unfavorable impact from advancement evolution by accelerating the transformation of innovation-driven internal combustion and creating new kinetic energy and fostering new business forms; it is also necessary to coordinate regional structure upgrading and industrial internal structure adjustment, promote the effect of structural rationalization, strengthen internal and external linkages, and improve the overall effectiveness of marine fisheries.

Massive carbon emissions and environmental pollution from electric power industries make China accelerate the promotion of renewable energy power. Since then, Tradable Green Certifications (TGCs) and Renewable Portfolio Standard (RPS) systems have been adopted as a main energy policy to deepen the current power sector reform. A recursive computable general equilibrium model will be constructed to explore the impacts of TGC and RPS policies under 4 scenarios. The simulation results show that the implementation of TGC and RPS policies will reduce 1.12 Bt-CO2 emissions and 1040.31 Mtce energy consumptions at most in 2030. Moreover, the TGC and RPS policies will help to rebuild a sustainable economic structure by the limitation of fossil energy consumption and output; especially in coal and oil industries, the spread of TGC and RPS makes renewable energy electricity become fungible for other energy generation. Nevertheless, this policy will also cause a lot of economic loss in gross domestic product through the huge deterioration of fossil energy-related industries, which will be expressed in the dramatic decline of output, consumption, and import and export trade. Additionally, we discover that the RPS level will have a significant influence on TGC prices: the higher the RPS level, the more the expensive TGC price. Overall speaking, the RPS level of 30% would be a better choice for the balance between the development of renewable energy and the negative impact on macroeconomics. It is recommended that the implementation of the TGC and RPS level should be with other economic policies to reduce the negative effects.
