This paper proposes an optimal design model of microgrids with small-scale photovoltaic systems (SS-PVs) and storage batteries for industries along with three economic evaluation indicators. The proposed indicators are levelized energy cost, emission reduction benefits, and payback period. They are combined to comprehensively evaluate economic performances and investment risk of the microgrids. The...
Commercial distributed PV systems present different economic values for each stakeholders in the electricity industry. While societal valuations are driven by PV performance and environmental cost, the private value depend on commercial arrangements between participants and PV policies. These estimations can play an important role helping to tailor PV policies that maximize PV benefits for industry...
This paper investigates China's reinsurance regulation's necessity, measurement and efficiency by market price distortion, indirect regulation mode and Kaldor-Hicks Criterion respectively.

This paper examine the various committed new technology and improve logging activities ascribed in the `Logfisher' Practice (LP) rather than Conventional Practice (CP). The result of cost analysis shows that the cost constitutes under LP is higher than under CP. Incremental average per ha total cost rose by 46.86% to RM13,576/ha. While the incremental average per m3 total cost increased by 57.41%...
Based on specifying the definition of the externality theory, this paper make a empirical analysis of the externality of education and training industry by the Feder model, obtain education and training spillovers and differences in the relative marginal productivity of factors of production. Besides, as education and training has strong externalities, it has positive external effects on the development...
It is difficult to accurately analyze forecasting of tax income. This thesis establishes a tax forecasting model based on BP neural network to analyze impacts imposed on tax income by changes of the following economic factors: industrial added value, total investment in fixed assets, total volume of import and export, total volume of fiscal expenditure, resident consumption level, etc. The thesis...
Telecom industry plays an important role in national economic development because of its extensive external economic advantages; thus, it is very important to discuss the pricing methods of the telecom services. According to the economic analysis of the two circumstances of the telecommunications businesses, which is based on realizing the maximum of social welfare (from the standpoint of consumers)...
In this study, a combined treating process (neutralization, electrolysis, ozone oxidization, coagulation and cinder adsorption) was introduced to investigate the possibility of degradation of concentrated azo dye wastewater. The optimum operation parameters were obtained through small-scale bench tests and pilot-scale tests, and then were put into operation. The experimental results showed that the...
With the rapid development of the national economy, many buildings unable to meet the requirements of structure perfection degree and decoration form because the economic conditions and construction techniques constraint. Especially the buildings built in 50-70, which most are masonry structure, and face the alternative that one is reconstruction and the other is reinforcement to meet the new function...
