Regional disparities in the Chinese economy. An emergy evaluation of provincial international trade

Abstract

Due to different resource endowment, geographical features, culture and population size, different regions are facing different challenges and therefore need to adopt different strategies toward sustainable development. China's Eastern, Central and Western provinces are taking different policies on international trade in order to boost their economy. This paper tries to investigate what extent a province receives a trade advantage and the corresponding environmental resource flows by employing an emergy accounting method for the period of 1993-2012. Three emergy trade indicators (Exchange Emergy Ratio, Emergy Benefit Ratio and Opportunity Ratio) were calculated along with conventional monetary indicators, to describe the benefits and losses in trade over the investigated period. The results show that the total trade volume of each province increased, but the trajectory of growth has a clear regional disparity. Eastern provinces gained economic advantages during the investigated period, while western provinces did not. The key finding is that benefits in terms of resource availability and work potential are not always in line with monetary advantages. Foreign trade partners received more advantages than their Chinese counterparts although Eastern Chinese provinces performed much better that both Central and Western Chinese provinces. Policy suggestions are then raised so that more sustainable trade policies can be prepared by considering the local realities.

Entrepreneurs and Environmental Sustainability in the Digital Era: Regional and Institutional Perspectives

“…China has faced serious challenges such as resource depletion and environmental degradation [8]. Although the different regions in China are facing various challenges due to different resource endowment, geographical features, economic level and population sizes [9], the common problem of China is the low level of ecological construction including poor environmental protection [10]. Therefore, the government must develop a green economy and increase investment on environmental protection in the future.…”

The Influence of Import Substitution on Regional Positioning in the System of International Economic Relations

“…); for metallurgical complex -Italy, for leather products and shoes industry -Turkey, for mechanical engineering -Ukraine. 4 Thereby, the goal of effective import substitution in the Rostov region is the advanced development of some industries, which are selected taking into account national priorities, specialization and resource potential of regional economy. These industries are following: machine-tool construction (import dependence level is 90 %); radio and electronic industry (82 %); light industry (72.5 %); oil and gas mechanical engineering (24 %); avia- tion industry (helicopter construction) (24 %); power engineering industries (19.7 %); chemical industry (9.7 %).…”

“…The paper demonstrates that various regions of national economy, taking into account their realities, take different foreign trade courses for the purpose of economic development. [4]. But there are not enough research on how import substitution in a region improves the positioning of its economy in a system of international economic relations.…”

Evaluation of interaction between chosen indicators of development of regions in Ukraine

“…Ran et al (2007) indicate that, although FDI still has a positive effect on China's economy, this investment leads to the widening of regional disparity and, as a result, to the emergence of "backward" regions. Tian et al (2017) study peculiarities of the impact of international trade on economic development of Chinese provinces. It is found that foreign trade has the positive influence on the country's regions, but its effect is not equal for all provinces.…”
