Empirical analysis of carbon tariff's effect on the export structure of China's manufacturing industry and social welfare based on the GTAP model

In recent years,carbon emissions have gradually evolved from an environment issue into a political and economic one.Carbon tariff has brought about new trade barriers of developed countries,and in order to enhance the industrial competitiveness of developed countries,it will produce unfavorable impact on developing countries.Concentrated on the manufacturing industry,which is the most intensive high-carbon industry in China's export structure,this article studies the relationship between carbon tariff policy and industry structure of export trade and builds up a relation between climate change and international trade.First,by means of establishing a partial equilibrium model,it applies geometric analysis and mathematical analysis to compute the impact on China's manufacturing export trade and the consequences of the introduction of the US carbon tariff to China's manufacturing industry that has already imposed a domestic shipping carbon tax.Furthermore,with the application of the GTAP model,it estimates the overall economic and welfare effects on China's manufacturing industry if the US and Europe introduce carbon tariff by means of four ways,and then analyzes the influence on China's manufacturing industry export structure and social welfare as well.The result shows that the introduction of the US carbon import tariff lowers China's export price and export volume,and the implementation of a domestic carbon tax justifies a higher export price and a lower export volume for China.However,the degree of export reduction is smaller than that under the effect of the US carbon tariff.In the case of developed countries imposing carbon tariff on China's energy-intensive industries,such as chemical rubber products,oil and coal-processing industry and paper industry,whose export would be reduced,the negative impact on the paper industry is the severest,which will decrease the paper industry's export ranging from 1.79%to 6.05%,whereas the other industries' export will increase.Anyhow,it will promote China's manufacturing industry to adjust the export structure to a certain extent.In addition,it will lead to a decrease in China's welfare,with a decrease between $2,134 billion and $8,347 billion.Finally,this paper provides information on international coordination,export structure adjustment and green manufacturing adjustment as a reference for the development of China's manufacturing industry.

Impact of the green credit policy on external financing,economic growth and energy consumption of the manufacturing industry

China attempts to achieve energy conservation,emission reduction and environmental protection through the implementation of the green credit policy,but its implementation impact is still controversial.An important content of the green credit policy is to require banking and financial institutions to tighten the credit exposure of industries of‘high pollution and high energy consumption’and industries with overcapacity,so as to use economic leverage to curb their blind expansion and reduce energy consumption by controlling external financing.This paper examined the impact and the lingering effects of the green credit policy on external financing,economic growth and energy consumption in the manufacturing industry,which was most influenced by the green credit policy,from 2003 to 2016 by using the DID method.Furthermore,this paper estimated the dynamic endogenous relationships among external financing,economic growth and energy consumption with two-step system GMM model to investigate the influential path of the green credit policy.The results showed that:the green credit policy had a significant negative impact on the external financing of manufacturing industry,but its negative impact on the economic growth and energy consumption of manufacturing industry was not statistically significant,and the effect of the green credit policy had a dynamic feature of weakening with time.Additionally,in the manufacturing industry,there was a bilateral causal relationship between the energy consumption and economic growth of the control group industry and the processing group industry.There was a bilateral causal relationship between the economic growth and external financing of the control group industries in the manufacturing industry.There was a unilateral causal relationship between the economic growth and external financing of the processing group industries in the manufacturing industry,while the external causality existed between the control group industries and the processing group industries in the manufacturing industry.The causal relationship between the financing and energy consumption was not statistically significant.At present,the transmission path of the green credit policy is that the green credit policy controls external financing,then affects economic growth and ultimately inhibits energy consumption,but the effectiveness of the path is not statistically significant.The conclusion of this paper provides policy reference and scientific basis for the adjustment and improvement of green credit.

Financial crisis and sustainable development of Chinese manufacturing industry

Sub-prime lending crisis has become an international fi nancial crisis, which is evolving into an economic recession sweeping across the West. Financial crisis leads to the demand reduction in western countries, and as the largest manufacturing country, China must face overproduction. The role of China as "world factory" determines that fi nancial crisis will severely attack Chinese manufacturing industry. The unsustainable development of Chinese manufacturing industry is mainly reflected in the following aspects: heavy dependence on export, low-level manufacturing link, lack of modern service industry and high-tech industry, weak independent innovative ability, unsustainable exploration of heavy-pollution resources, and lack of international famous brands. How to transform crisis to opportunities is an urgent research topic. Under the circumstance of financial crisis, Chinese manufacturing industry has more external drives to change the current situation. Therefore, financial crisis becomes not only an opportunity for Chinese manufacturing industry to improve itself based on the existing accumulation but also a chance for China to transform from "world factory" into a powerful nation of manufacturing industry in the world.

I t has a lot of functions, such as market management, production planning, finan ce administration, quality control, personnel matters administration, electronic data exchange, business flow optimization and policy decision sustenance. With economy globalization, market internationalization, various and individual requ irement, modern enterprises become more and more to need ERP systems. Different trade patterns, scales,modes of operation and characteristics of products, the c onstruction of the ERP system is different. This article analyzes and discussess the characteristics of production and operation, internal administration models and market requirements about the enterprises that produce communication applia nces. Each piece of production made in the enterprises have small value and vari ed specifications. The enterprises design and produce things according to the or ders from customers. And the quantity of production in a batch is big. And the c ycle that customers remand delivering the goods is short. Assigning material and producing according to orders is this kind of enterprise’s principal organizati on pattern. The enterprises buy material according to orders, and negotiate a pr ice in many ways. In connection with this kind of enterprises which produce non -standardized parts, we put forward the construction of ERP system and take som e particular measures. First, putting the ERP system into effect can make enterp rise’s goods flow, fund flow, information flow unblocked in time and accurately, respond the change about market quickly and promote the selling of production. Second, it can make enterprise control some links efficiently, such as producin g, selling, operation plan and so on, and can arrange manufacturing reasonably. Third, it can make enterprise achieve official business automation, improve ente rprise’s administration and official business’ efficiency, supply multiple infor mation service for enterprise’s leads and raise enterprise’s comprehensive image such as trademark, quality, service and so on. Therefore, establishing the ERP system’ structure and putting it into effect is significant to enterprise’s runn ing.
