Green Technology Spillover And Urban Agglomerations Economic Development In China

With the acceleration of the city urbanization process, urban agglomeration has become the main mold of our country’s regional economic development and competition. According to our country’s future urbanization development ideas, urban agglomeration will become the main space vector of urbanization during the "Twelfth Five-Year Plan" period, and it is a key driving force for our country’s sustained and rapid economic development. Since the industrial revolution, the traditional model of economic development has consumed large quantities of coal, oil, natural gas and other fossilized high-carbon energy, and discharged a large amount of greenhouse gases such as carbon dioxide into the atmosphere, leading to global warming and climate change problems. All of these have become a threat to the survival and development of the modern human. Consequently, the growth of green economy, led by green technology, has become the focus of attention in many countries. Green technology innovation and diffusion is the only way to solve the double challenges of global climate changes and the global energy crisis. The study of green technology diffusion and spillovers therefore warrants a particular concern.With regards to the recent increase of environmental protection ideas and measures, our country’s study on green technology diffusion and spillovers began in 20th century 90 years, and green technology has since gradually matured. But compared with developed countries, the green technology stocks of China are low, and there are large differences between the regional green technical stocks. It is necessary for domestic scholars to study and analyze the effect of green technology diffusion and spillovers especially in the economic development of urban agglomeration effects on China’s regional and also to explore how to achieve economic development through green technology knowledge. Given these considerations, this research is significant in three ways. First, it is beneficial for our country to strengthen the innovation of green technology and to promote the progress of science, technology, and economic development. Second, it is good for our country to increase the research efforts on green technology and green technology spillover riches research achievements; Finally, it is beneficial to promote the urban green economic development of our country in order to strive to promote balanced and sustainable development of the cities in the megalopolis.This paper’s main research object is urban agglomeration. Using the endogenous growth theory and system theory analysis method, this paper analyzes the green technology overflow facts of China’s typical urban agglomeration and constructs the index system of the influence factors of green technology spillovers. Through the empirical study of threshold effects in the country and urban agglomeration of green technology’s spillover to economic growth, the study puts forward the policy recommendations of national and urban agglomeration development of the green economy and obtains the following conclusions:First, according to the number of China’s green technology spillover measured, this paper describes the spatial distribution and technical characteristics of Chinese provincial and urban agglomeration’s green technology spillover, and reveals the law between Chinese green urban agglomeration and its technological spillover. Looking at the papers on a province level, Beijing, Jiangsu, Shanghai and Guangdong each have more than 650 green technical papers, with Beijing leading the crowd at 1498 papers. Calculated based on urban agglomeration, the green technology spillovers of China’s top ten urban agglomerations all show growth trends, and the amount of the green technology spillover in the Beijing-Tianjin-Heibei and Yangtze River Delta regions is far more than other urban agglomerations. The west side of the Straits and Guanzhong urban agglomeration growth rates are relatively small, which indicates a lack of driving force of green technology innovation.Second, through economic inspection on Chinese green technology spillover, this paper finds that the green technology innovation’s effect on economic growth is significantly negative. Regional green technology spillover lacks economic attractiveness. Using the number of papers in green technology as the proxy variable, this paper concludes that there exist regional differences in the relationship between green technology and economic growth. Green technology spillovers occur mostly in more economically developed areas and more mature urban agglomerations. Green technology innovation in the center city of an urban agglomeration has an obvious U-type relationship with economic growth, which is not obvious in the surrounding city.Third, this paper constructs Chinese green technological diffusion model, obtains the conditions for Chinese transition to green technology, and proposes strategies to improve green technology spillover. Some strategies include the idea that green technology spillover should increase the emission rate and the wage rate ratios and improve both green technology stock and general technology stock ratios. Output growth rate is not only related to the ratio of the discharge rate and the wage rate, but also related to time. If the government forces enterprises to adopt green technology when their green technology stocks are relatively low, output growth rate will drop accordingly. Since the reality of most cost saving technology polluted and the implementation of cost-saving technology, pollution appears to have increased slowly. Due to the developed countries have lower adopt conditions, China’s implementation of green technology started relatively late, and the pollution emissions reduced compared with the developed countries.Fourth, this paper analyzes the hierarchy between the influencing factors of green technology spillover, establishes the influencing factors’index system of the green construction technology spillover, and establishes an economic growth threshold model of green technology spillover in line with China’s actual conditions. According to the Chinese panel of economic data, the economic growth threshold effect on the green technology spillover was analyzed on the national level. The Beijing-Tianjin-Hebei, Yangtze River Delta, the Pearl River Delta, and the Shandong Peninsula urban agglomerations underwent threshold test and effect analysis. The respective thresholds were estimated based on GDP per capital of each area and the tertiary industry ratio of green technology spillovers, providing development direction for urban agglomerations and implementation approaches for the green economy.Fifth, this paper analyzes developed countries, including the United States, Britain, and Japan, on the experience of advanced development of green economy, such as green credit policy, strengthening the innovation of green technology, and cultivating the public’s awareness of low carbon, etc. China must strengthen overall co-ordination, increase government investment, and play a leading role in establishing public awareness of green consumption. According to the green economy development, China must put forward the following policy suggestions targeted at urban agglomerations, such as optimizing their industrial structures, improving their energy efficiency, strengthening their technological strength, improving their efforts to coordinate urban environmental advocacy groups, increasing their environmental protection awareness, establishing regional economic coordination mechanisms, and implementing consumer policy recommendations.
