China's Economic Structure:Changes and Challenges

This paper elaborates the changes in key aspects of China's economic structure including industrial structure, demand structure, regional structure, income distribution and foreign trade, discusses the challenges confronting China's economic structure, and proposes policy recommendations on addressing these challenges.

Chinese Economic Structure and SDA Model

With the rapid economic growth, Chinese economic structure has greatly changed. In this paper we propose a new structural decomposition analysis (SDA) model and use it to analyze the Chinese structure change from 1981 to 1995 on the basis of input\|output tables of China with 18 sectors at current price and at constant price, constructed by us.

Value Circulation,Economic Structure,and the New Development Paradigm:A Theoretical Framework of Political Economy and International Comparison

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.

Construction of Regional Economic Vitality Model

Regional economic vitality reflects the scale and development potential of a region’s economy.It largely determines the development of the city,and is also affected by many factors such as population competitiveness,corporate competitiveness,market vitality,innovation vitality,and environmental vitality.A pilot model was constructed with Hebei Province as the inspection area.Quantitative measurement of regional economic vitality was made by finding 21 indicators that indirectly or indirectly affect the economic vitality of Hebei Province.By analyzing the data of 21 indicators for nearly 10 years,the time series clustering is used to achieve the dimensionality reduction of the indicators.After the dimension reduction,it is divided into four categories:overall scale,development potential,market vitality,and innovation vitality.Construct the economic vitality structure model of Hebei Province,and determine the four types of contribution to economic vitality and compare them.On this basis,more accurately grasp the indicators that affect economic vitality and work out reasonable and effective action plans.From the perspective of human resources and corporate vitality,analyze how the action plan accurately affects the economic vitality of Hebei Province[1].The 11 cities in Hebei Province are the target of regional economic vitality.The economic vitality structure model constructed uses the required contribution value to select priority indicators.Finally,the six indicators of GPD,GPD growth rate,fiscal revenue,fiscal revenue growth rate,number of industrial enterprises above designated size,and total profit of industrial enterprises above designated size were established for eleven cities in Hebei Province to construct a TOPSIS scoring model,and calculation rankings were conducted through MATLAB.Results The top three cities were Shijiazhuang,Tangshan and Cangzhou.

日元汇率波动新态势

Concurrent with the interest rate hike by the Federal Reserve(Fed) at the beginning of 2022, the Japanese yen entered a fast track to depreciation. 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.

Research on the Development of Economy and Farmers' Income Growth in Heilongjiang Province

Nowadays, increasing farmers＇ income is not only related to the development of rural economy, the improvement of farmers＇ lives and countryside stability but also related to the overall situation of economy and social development. Heilongjiang is a big agricultural province, however, the increase of farmers＇ per capital net income is rather slow in the last few years. On the basis of Lewis dual economic structure theory and our province＇s actual situation, the paper proposed the concrete countermeasures to increase farmers＇ income, so as to promote the development of economy.

Digital Economy Enables High-Quality Economic Development: Theoretical Mechanisms and Empirical Evidence

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.

Economic impact of land finance and subsequent risk response

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.

基于公路客流的中国城市网络结构与空间组织模式（英文）

The use of multi-perspective and multi-scalar city networks has gradually developed into a range of critical approaches to understand spatial interactions and linkages. 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.
