Land use in the Changjiang （Yangtze） River Basin （CRB） since the 1950s has experienced these changes. Industrialization has been the most powerful force of the change in the regional development of the CRB. Virtually all regional resources were put into this effort to modernize the industrial production and urban construction systems of the CRB whose industrialization and urbanization has been a success story, with impressive structural change in both production and land use. These changes are evident ih modem urban areas, but even more in traditionally rural areas. The regression analysis of regional development in the CRB over an extended period shows that the dominant factor in regional land use change is widespread industrialization in rural areas rather than the expansion of urban area. Thus, urbanization has had a limited influence on land use change in the CRB. A major task in realizing more sustainable land use in the future development of CRB is to relocate industrial activities from rural to urban areas.展开更多

Since the new century, the Chinese government began to adjust serious distorted urban-rural relations. New rural construction, total abolition of agricultural tax, the construction of modern agriculture and other major strategic decisions have been introduced; free compulsory education in rural areas, the new rural cooperative medical care, rural public infrastructure, cultural services and other specific measures have been rolled out building. But these still can not slow down our growing urban-rural gap, China＇ s economic and social development is still running under the urban and rural pattern, and the trend has increased.展开更多

In this paper, the present status of economic structure of Shaanxi Province is analyzed, and available primal problem is indicated. There have been a lot of problems in economic structure of Shaanxi Province, mainly including slow tertiary industry development, comparatively grave unbalance of light and heavy industries proportion, lagged development in high and new technology industries, high industry convergence degree, low scale effect, slow agriculture expanding and so on. Meanwhile, homologous countermeasure is given in this text： we should develop tertiary industry with tourism as the leading role energetically to promote industrial hierarchy, impulse structural rationalization of foreign trade through international cooperation and competition, accelerate the industrialization, promote industrial structure upgrade, develop the high and new technology industries quickly, accelerate the promotion of industry scale effect and expedite expansion of industry colony. We should also develop superior industry, reduce industry convergence degree, and develop the agriculture energetically to promote the industrialization and modernization of agriculture. These points are given in the interest of supplying gist and reference to government in industrial structure adjusting and policy making.展开更多

Since November 2022, however, as the Fed slowed its tightening pace and as the Bank of Japan(BoJ)tweaked its monetary policy, the yen has regained some of the ground it lost. Overall, the yen has been characterized by strong volatility. The primary factor driving the fluctuations of the yen in the short term is the widening United States–Japan interest rate differential. From a mid-to-long-term perspective, the underlying reason behind the exchange rate movements of the yen is the BoJ’s monetary policy and the Japanese economy’s structural changes.The fluctuations of the yen are a mixed blessing for the Japanese economy;in the long run, however, they will do more harm than good. As for the world economy, turbulent yen fluctuations may trigger a fresh round of currency competition and disrupt the financial markets. Looking ahead, for long-term healthy economic development, Japan needs to cut down on its exchange rate dependence and restructure and upgrade its economy.展开更多

Input to the model includes indexes of economic structure and development, water resource utilization, wastewater and pollutant discharge, and investment in wastewater treatment. The model, which consists of production structure and industrial structure optimization modules, was applied to the Guanzhong region in the middle reaches of the Huanghe (Yellow) River basin in China. By evaluating several alternative production and industrialization schemes, the modal indicate that water pollution will get worsen though wastewater treatment improves if the economy continues to develop at the planned speed without structural adjustment. However, the results also show that not only economic goals but also water resource protection and pollution control targets can be achieved under an alternative, recommended production and industrial structure. This example illustrates that economic development and environmental protection can be improved coordinately by the regional multiple objective water resource and economic optimization model. It provides an operable approach to the simultaneous sustained development of water resources and economic growth.展开更多

Based on the economic model of urban spatial structure and applying panel data in Shandong Province, the paper concludes. Economic growth and transition of economic structure have played the most powerful role in urban expansion. An increase in population helps the core to extend. Increasing agricultural productivity can provide a countervailing force. An increase in transportation costs will limit urban expan- sion. An increase in the marginal productivity of land in housing production will increase urban expansion. Fiscal and taxation policies also have encouraged the extensive shift of cultivated land into build-up area. This paper also suggests that if high rate increasing GDP is needed, the urban core will continue to expand. The government should take measures to improve the rapid growth of the city.展开更多

The mismatch is exhibited at the supply side and arises from structural contradictions and must be addressed through reforms. Supply-side structural reforms can be analyzed at the levels of firms, industries and government to arrive at theoretical and systematic conclusions that offer practical guidance. Based on this perspective, this paper proposes policy recommendations on how to deal with zombie firms, reduce cost for manufacturing companies, deepen SOE reforms, eliminate overcapacity, implement ＂Made in China 2025＂ and Internet＋ strategies, promote Beijing-l^anjin-Hebei integrated development, as well as develop the Yangtze River Economic Belt and the old industrial bases of the northeast.展开更多

But with the further promotion of China＇s reform and opening-up and intensification of the further improvement degree, the main factors influencing a regional economic growth constantly change. This paper utilizes the relevant data of Sichuan to set up the econometric model and quantitatively studies the factors influencing economic growth of Sichuan. Through comparing the greatness that each factor influences the economic growth of Sichuan, the paper takes system changes as leading factor to influence the economic growth during 1984-2003 of Sichuan. At the same time, the upgrading of industrial structure will be a core of economic growth in the future, and the scientific and technological progress is the potential force of economic growth.展开更多

In particular, road linkages represent key characteristics of spatial dependence and distance decay, and are of great significance in depicting spatial relationships at the regional scale. Therefore, based on highway passenger flow data between prefecture-level administrative units, this paper attempted to identify the functional structures and regional impacts of city networks in China, and to further explore the spatial organization patterns of the existing functional regions, aiming to deepen our understanding of city network structures and to provide new cognitive perspectives for ongoing research. The research results lead to four key conclusions. First, city networks that are based on highway flows exhibit strong spatial dependence and hierarchical characteristics, to a large extent spatially coupled with the distributions of major megaregions in China. These phenomena are a reflection of spatial relationships at regional scales as well as core-periphery structure. Second, 19 communities that belong to an important type of spatial configuration are identified through community detection algorithm, and we suggest they are correspondingly urban economic regions within urban China. Their spatial metaphors include the administrative region economy, spatial spillover effects of megaregions, and core-periphery structure. Third, each community possesses a specific city network system and exhibits strong spatial dependence and various spatial organization patterns. Regional patterns have emerged as the result of multi-level, dynamic, and networked characteristics. Fourth, adopting a morphology-based perspective, the regional city network systems can be basically divided into monocentric, dual-nuclei, polycentric, and low-level equilibration spatial structures, while most are developing monocentrically.展开更多

The decomposition forms, which are used to measure the contribution of a specific determinant, are not unique due to the existence of a multitude of equivalent forms, irrational due to the weights of different determinants not matching, inexact due to the existence of large interaction terms.In this paper, a decomposition method is derived to overcome these deficiencies, and we prove that the result of this approach is equal to the Shapley value in cooperative games,and so some properties of the method are obtained. Beyond that, the two approaches that have been used predominantly in the literature have been proved to be the approximate solutions of the method.展开更多

文摘This study constructs a theoretical framework for understanding the new development paradigm based on value circulation and the reproduction theory of Marx.According to these theories,the essence of economic circulation is value circulation,the core of which is mutual matching among the structures of technological,distribution,demand,and production.We adopted a three-sector reproduction model with fixed capital to understand different development paradigms under various combinations of the four aforementioned structures.On this basis,we use the 1957-2017 input-output table to construct the three-sector tables and explain the logic of China’s economic structure change and the characteristics of the resulting circulation patterns.We also compared the economic structures and circulation patterns of the United States and Japan with those of China to shed light on China’s choice of future economic circulation patterns and the new development paradigms.

文摘Over the past two decades, structural decomposition analysis (SDA) has developed into a major analytical tool in the field of input-output (IO) techniques, but the method was found to suffer from one or more of the following problems. The decomposition forms, which are used to measure the contribution of a specific determinant, are not unique due to the existence of a multitude of equivalent forms, irrational due to the weights of different determinants not matching, inexact due to the existence of large interaction terms.In this paper, a decomposition method is derived to overcome these deficiencies, and we prove that the result of this approach is equal to the Shapley value in cooperative games,and so some properties of the method are obtained. Beyond that, the two approaches that have been used predominantly in the literature have been proved to be the approximate solutions of the method.

文摘Digital economy has become the primary motivation for high-quality economic development.Upon comprehensively analyzing the connotation of digital economy,this paper constructs an evaluation system from development environment,digital industrialization,industrial digitalization,and digital governance to measure China's digital economy index from 2016 to 2018 using the entropy-based TOPSIS method.Also,based on the improved Feder dual sector model,this paper discusses the theoretical mechanism of digital economy promoting high-quality economic development directly and through improving economic efficiency and economic structure,and carries out an empirical test.According to findings,on the one hand,China is scaling up digital economy and accelerating digital transformation;on the other hand,the greater the likelihood that high-quality economic development is constrained by low economic efficiency and unreasonable economic structure,the greater the role of digital economy in promoting high-quality economic development.Therefore,this paper puts forward recommendations for China's high-quality economic development,such as advancing new infrastructure construction,developing digital economy,improving economic eficiency and economic structure,and transforming the government governance model.
文摘In China,land finance is actually an endogenous factor in economic growth.As a kind of non-traditional,informal government revenue in China’s economic transition process,land finance is unstable,non-standard and unsustainable,and it simultaneously makes the current land-finance dependent growth mode difficult to maintain.The paper firstly analyzes the impact of the land finance on China’s economic growth and economic structure change followed by discussing the possible risks in post-“land finance”period.It then put forward some suggestions to deal with the problem.The analysis shows that land finance exacerbates the economic fluctuation,bringing in the increase of government public expenditure and economic growth in the short term.Nonetheless,in the long term there is no significant effect,and it could gradually lead to a more unreasonable economic structure.In the post-“land finance”period,if we do not take precautions in advance,it will restrain the sustainable development of China’s economy and society.
