The present manufacturing situation of China’s thermal power generation equipment By the year 1995. development of China’s electric power industry has experienced a course of a hundred years. Over a period of the initial 50 years. China’s development of electric power was slow. At the time of 1949, the total installed capacity in China was 1,850 MW and the electricity generated was only 4.3 billion kWh. During the past 46 years after 1949, her展开更多

The competition between China and India is a typical one between economic institutions. This paper, by making a diachronic analysis on their courses of development, tries to justify the importance of adopting an economic institution suitable to the situation of a country.展开更多

文摘Green technology innovation meets the dual expectation of innovative development and green development perspectives.Under the canonical demand-pull and policy-push theories,a long-term mechanism for green technology innovation could be formed through upstream policy push and downstream demand-pull.Leveraging China's regional carbon emission trading scheme pilots as a quasi-natural experiment,this paper examines the policy-push and demand-pull effects on innovation in renewable energy patents.The data pertain to the city-level renewable energy patents from 2000 to 2020.Based upon the triple difference-in-difference method,results suggest that both policy-push and demandpull factors exert positive effects on innovation.This paper further explores the practical and theoretical implications of green technology innovation under the new development perspective.
