Impact of coupling coordination development of port and city environments on urban economic competitiveness:Evidence from the coastal port cities in eastern China

Promoting the coupling coordination development of port and its hinterland city environments is an important way to improve urban economic competitiveness.Based on relevant data of 13 coastal port cities in eastern China from 2000 to 2018,this study explores the coupling coordination development of port and city environments and its impact on urban economic competitiveness by constructing the coupling coordination degree model and the panel threshold model.The research results show that:(1)In terms of the coupling coordination development of port and city environments,most coastal ports and their hinterland cities are in a state of moderate or serious disorder.Overall,the degree of coupling coordination of port and city environments needs to be further improved;(2)The coupling coordination degree of port and city environments has a significant impact on urban economic competitiveness,and this effect gradually increases with the development of the ports and the urban economy.Among the variables that impact the urban economic competitiveness,fixed assets investment and foreign trade are significant factors that can enhance urban economic competitiveness.(3)At present,there is a“U-shaped”relationship between the coupling coordination degree of port-city environments and the urban economic competitiveness.This relationship lies on the right side of the inflection point of the“U-shaped”curve.Therefore,following the concept of assigning priority to ecological development,expanding fixed assets investment and actively developing foreign trade can further enhance the urban economic competitiveness.

Effect of Bt traits on transgenic rice's growth and weed competitiveness

Transgene escape could lead to genetically modified rice establishing wild populations in the natural environment and competing for survival space with weeds.However,whether the expression of the Bacillus thuringiensis(Bt)gene in rice will alter the relationship between transgene plants and weeds and induce undesirable environmental consequences are poorly understood.Thus,field experiments were conducted to investigate the weed competitiveness and assess the ecological risk of transgenic Bt rice under herbicide-free and lepidopterous pest-controlled environments.Results showed that weed–rice competition in the direct-sowing(DS)field was earlier and more severe than that in the transplanting(TP)field,which resulted in a significant decrease in biomass and yield in DS.However,conventional Bt and non-Bt rice yield was not significantly different.The weed number,weed coverage ratio,and weed diversity of conventional Bt rice were significantly higher than those of non-Bt rice at the early growth and mature stages,especially in DS plots,suggesting that Bt traits did not increase the weed competitiveness of transgenic rice and had no negative effect on weed diversity.Grain yield and weed number varied between different hybrid rice lines,but those differences were insignificant between Bt and non-Bt rice.The number of insects increased with the increase of weeds in hybrid rice plots,whereas the insect number and diversity did not display a significant difference between Bt and non-Bt rice.Therefore,the ecological risk of transgenic Bt rice is comparable to non-Bt rice.

Does Environmental Regulation Weaken Industrial Competitiveness?Inspirations from China’s Iron and Steel Sector

China＇s economic growth is heavily influenced by exports, while reconciling environmental regulation and economic growth requires handling the relationship between environmental regulation and industrial competitiveness well. The effects of environmental regulation on industrial competitiveness are largely subject to the institutional design of environmental regulation. Despite numerous studies on the relationship between environmental regulation and industrial competitiveness, a consensus has yet to be reached. Aside from differences in research methodology, these studies failed to give sufficient consideration to the impact of environmental regulation on industrial competitiveness. Such effects can be negative or positive depending on the design of environmental regulatory policy. This paper has investigated the relationship between environmental regulation and the competitiveness of China＇s iron and steel industry and discovered that tighter environmental regulation does not diminish the competitiveness of the iron and steel industry since the policy design of environmental regulation accommodates the tolerance of advanced production capacity and includes a reasonable cost sharing mechanism. This discovery is of important reference for China to develop rational policy design to balance the relationship between environmental regulation and industrial competitiveness.

Export competitiveness of agricultural products and agricultural sustainability in China

The competitiveness of a country’s agricultural products is not only related to its capacity to export agricultural products,but also to the sustainability of its agricultural sector.How to improve the international competitiveness of a country’s agricultural products while maintaining the sustainability of its agricultural sector is a practical problem of great urgency for a country with a large agricultural sector such as China.With this in mind,this study should have a considerable policy and practical significance.We used two evaluation indices,namely trade competitiveness(TC)index and revealed comparative advantage(RCA)index,to measure and analyze the international competitiveness of six China’s representative agricultural products,i.e.,live pigs,live chickens,live cattle,apples,tea,and beer,and to examine the changing trends of these products’competitiveness during 1994-2013.The results indicate that the export competitiveness of China’s agricultural products is weak and likely to deteriorate further.However,some traditional agricultural products with distinctive regional characteristics,for example,tea and live pigs,are relatively strong internationally.To this end,China should vigorously promote the production and foreign trade in traditional agricultural products with distinctive regional characteristics.At the same time,comprehensive measures should be taken to enhance the international competitiveness of disadvantaged agricultural products.

Strategic thinking on improving the environmental competitiveness of Chinese enterprises

Environmental competitiveness, price competitiveness and non-price competitiveness make up the undivided vital part of product＇s competitiveness. Environmental competitiveness can not only help improve the enterprise＇s key competitiveness directly, but also strengthen it indirectly by improving the products＇ price competitiveness and non-price competitiveness effectively. Instead of being confined to the product itself, there are several element＇s that can determine and influence the product＇s environmental competitiveness, including the manufacturing process, the management of enterprise＆the life circle of the products, etc. Measuring these elements by setting “environmental suitable degree ”, and building up the echelon model to evaluate the environmental competitiveness can help us see about the standard of the enterprises＇ environmental competitiveness. Though many of the national enterprises have price competitiveness to some extend, restricted by all kinds of elements like systems, techniques, policy, the enterprises are weak in environmental competitiveness. Beginning with systems redesign, carrying out the sustainable development, strengthening inner enterprises management, making more efforts on technique innovation, and widely publicizing and teaching the ecological concept, Chinese national enterprises can improve their environmental competitiveness and improve their key competitiveness.
