A Review on China’s Transportation Development Theory from the Perspective of Regional Economics

Transportation is the lifeline of human civilization and an important component of the infrastructure for economic growth.As transportation is closely related to regional economic development,the summarization of China's transportation development theory from the perspective of regional economics will be conducive to clarifying the relationships between transportation and regional economic development and providing basic theoretical support for regional economic research and policy application.From the perspective of regional economics,China’s transportation development theory falls into two categories:transportation resource allocations,and the interactions between transportation and economic development.In recent years,there has been a trend toward the integration of transportation development research with regional economic growth,and a deeper understanding of the relationships between them has been achieved.

The End of Western Economic Growth Theory

Economics is a science that studies how the economy grows,so the theory of economic growth is the most important theory of economics.In the real market economy society,people achieve the goal of economic growth through two kinds of economic activities:production and transaction.Then a correct economic growth theory must be one that can explain both production and transaction economic activities.Just like Newton’s law of universal gravitation in physics,it can explain the motion law of all objects.For a long time,we have been dominated by the western economic growth theory of western mainstream economics.It is not difficult to find that it has a fatal defect,which can only explain production economic activities but not transaction economic activities.So it can’t explain the Chinese economy,and it can’t explain the western economy.The new economic growth theory proposed in this paper makes up for the defects of western economic growth theory,and it is the terminator of western economic growth theory.This is a revolution of new economics to traditional western economics.

The role of R&D and economic policy uncertainty in Sri Lanka’s economic growth

In this paper,we assess the role of investment in research and development(R&D)and economic policy uncertainty(EPU)in Sri Lanka’s economic growth experience.We do this by first determining which endogenous growth theories best explain the evolution of total factor productivity(TFP)in the country.Using historical time series data(1980–2018),we find that semi-endogenous growth theories best explain the evolution of TFP in Sri Lanka.This evidence suggests that R&D is critical to the country’s TFP expansion.We find that,through R&D,EPU has a crucial detrimental impact on TFP growth,although it is short-lived.Our findings are robust and have important implications for R&D investment and for moderating EPU.

The need for a new framework for the economic evaluation of health services in a national health scheme

The normative theory of economic evaluation and its welfare theoretic basis are deeply problematical and result in recommendations which are potentially unfair. The root cause of the problem is the set of assumptions behind the theory which posit behaviours and motivations that are not universal, and which exclude other behaviours and motivations that are potentially important. As falsification of assumptions may be evaded indefinitely this paper presents an alternative critique. We commence with six an- omalies with the theory which are attributable to the assumptions. The first three—the net present value criterion, the willingness to pay criterion and moral hazard—arise from welfare theory. The remaining three are associated with the present definition of cost, the concept of efficiency and the omission of sharing, which are common to most economic evaluation. We argue that these anomalies are indicative of a defective core theory and that they are equivalent to observations that conflict with a positive theory. In the final section we outline and illustrate a more general framework for decision making that is capable of overcoming the ano- malies we discuss.

Vital Nodes Evolution Study on Railway Network of Silk Road Economic Belt

In order to study the nodes importance and its evolution process of the railway network of SREB (Silk Road Economic Belt), we construct the network (RNSREB) based on Graph Theory, which focuses on the time intervals according to actually railway network, railway project under construction and the national railway network of medium-and long-term plan. The algorithms for vital nodes evaluation are analyzed, the evaluation method on nodes importance of RNSREB is proposed, the quantized values of each node are calculated with Pajek, and TOP20 core nodes of the network with different coefficients and time intervals are determined respectively. Then the evolution process of TOP20 critical nodes with 4 periods is contrasted and analyzed. It is indicated that some vital nodes newly discovered (Geermu, Maduo, Ruoqiang) should be concerned.

BASIC EQUATIONS, THEORY AND PRINCIPLE OF COMPUTATIONAL STOCK MARKET (Ⅲ)—BASIC THEORIES

By basic equations, two basic theories are presented: 1.Theory of stock's value v *(t)=v *(0) exp (ar * 2t); 2. Theory of conservation of stock's energy. Let stock's energy be defined as a quadratic function of stock's price v and its derivative , =Av 2+ Bv+C 2+Dv, under the constraint of basic equation, the problem was reduced to a problem of constrained optimization along optimal path. Using Lagrange multiplier and Euler equation of variation method, it can be proved that keeps conservation for any v,. The application of these equations and theories on judgement and analysis of tendency of stock market are given, and the judgement is checked to be correct by the recorded tendency of Shenzhen and Shanghai stock markets.

Analysis of Decoupling of Economic Growth and Resource Consumption in China’s Marine Fishery

The marine fishery resources are declining with the increase of fishing intensity, and the sustainable development of marine fishery economy has become the focus of attention. In this paper, the economic loss of marine natural fishery resources is taken as the undesired output. The SBM model is used to evaluate the economic efficiency of marine fisheries in 11 provinces and cities in China’s coastal areas from 2004 to 2015. Based on this, decoupling theory is adopted to analyze the spatial and temporal evolution pattern of marine fishery economic efficiency and resource consumption in various provinces and cities. The results show that: 1) Based on the perspective of time and space, the economic efficiency of marine fisheries in 11 provinces and cities along the coast of China is polarized and has not been effectively improved, indicating that the level of fishery economic development in China’s coastal areas is unbalanced;2) Based on the overall perspective, the overall economic efficiency of China’s marine fisheries is low, indicating that China’s marine fishery economy is developing at a slower rate;3) Based on the perspective of decoupling theory, the economic efficiency of marine fisheries in China and the consumption of fishery resources have shown a trend in the research period. The structure of China’s marine fishery industry, which is dominated by traditional fisheries, needs to be adjusted.

Vital Nodes Study on Airway Network of Silk Road Economic Belt

In order to study the nodes importance of the aviation network of SREB (Silk Road Economic Belt), we construct the network (ANSREB) based on Graph Theory that focused on the actually situation of civil aviation transportation of SREB. We analyzed the evaluation algorithms for nodes importance, proposed the evaluation method for nodes importance of ANSREB;the quantized values of each node (Degree, Betweennesss, Closeness) are calculated with Pajek and traffic data, and determined TOP 20 critical nodes of the network on two different conditions respectively (without and within International routes). Then we contrasted and analyzed the reason that affects the ranking of those vital nodes, which has the character of highly concentration of business and dominant status.

Quantum Model of Decision-Making in Economics

The paper designs a quantum model of decision-making (QMDM) that utilizes neuroscientific evidence. The new model provides both normative and positive implications to economics. First, it enhances the study of decision-making which is an extension of the expected utility theory (EUT) in mathematical economics. Second, we demonstrate how the quantum model mitigates drawbacks of the expected utility theory of today.

Information Models for Forecasting Nonlinear Economic Dynamics in the Digital Era

The aim of this study was to develop an adequate mathematical model for long-term forecasting of technological progress and economic growth in the digital age (2020-2050). In addition, the task was to develop a model for forecast calculations of labor productivity in the symbiosis of “man + intelligent machine”, where an intelligent machine (IM) is understood as a computer or robot equipped with elements of artificial intelligence (AI), as well as in the digital economy as a whole. In the course of the study, it was shown that in order to implement its goals the Schumpeter-Kondratiev innovation and cycle theory on forming long waves (LW) of economic development influenced by a powerful cluster of economic technologies engendered by industrial revolutions is most appropriate for a long-term forecasting of technological progress and economic growth. The Solow neoclassical model of economic growth, synchronized with LW, gives the opportunity to forecast economic dynamics of technologically advanced countries with a greater precision up to 30 years, the time which correlates with the continuation of LW. In the information and digital age, the key role among the main factors of growth (capital, labour and technological progress) is played by the latter. The authors have developed an information model which allows for forecasting technological progress basing on growth rates of endogenous technological information in economics. The main regimes of producing technological information, corresponding to the eras of information and digital economies, are given in the article, as well as the Lagrangians that engender them. The model is verified on the example of the 5th information LW for the US economy (1982-2018) and it has had highly accurate approximation for both technological progress and economic growth. A number of new results were obtained using the developed information models for forecasting technological progress. The forecasting trajectory of economic growth of developed countries (on the example of the USA) on the upward stage of the 6th LW (2018-2042), engendered by the digital technologies of the 4th Industrial Revolution is given. It is also demonstrated that the symbiosis of human and intelligent machine (IM) is the driving force in the digital economy, where man plays the leading role organizing effective and efficient mutual work. Authors suggest a mathematical model for calculating labour productivity in the digital economy, where the symbiosis of “human + IM” is widely used. The calculations carried out with the help of the model show: 1) the symbiosis of “human + IM” from the very beginning lets to realize the possibilities of increasing work performance in the economy with the help of digital technologies;2) the largest labour productivity is achieved in the symbiosis of “human + IM”, where man labour prevails, and the lowest labour productivity is seen where the largest part of the work is performed by IM;3) developed countries may achieve labour productivity of 3% per year by the mid-2020s, which has all the chances to stay up to the 2040s.

Socio-Demographic and Economic Correlates of Climate Change Coping and Adaptation Strategies: A Study on the Farmer Communities in Barisal District, Bangladesh

The major objective of the study is to apply Conservation of Resource (COR) theory for examining the influence of farmers’ socio-demographic and economic correlates upon their adoption of agricultural, economic and emotion-focused coping and adaptation strategies of climate change. An interview schedule developed from the COR theory was utilized for data collection. Using multistage cluster sampling technique, a total of 384 farmers were chosen from Agailjhara Upazila of Barisal District and interviewed through a predesigned structured questionnaire. For triangulation of the quantitative findings, the study employed case study technique to collect qualitative data from the respondents. The findings of the study demonstrate that the most common emotion- focused, agricultural and economic coping and adaptation strategies of climate change were social support seeking (79.69%), planting trees (71.35%), homestead gardening (52.08%), hydroponic farming/floating garden (46.88%), duck rearing (30.73%), saving (20.83%), self-insurance (18.75%), etc. Bivariate results indicate that age, ownership of land, income and ownership of television or mobile phone were found significantly correlated with the three variables, including economic, agricultural and emotion-focused coping and adaptation strategies of COR theory. Again, access to microcredit has relationship with economic and agricultural adaptation strategies. Furthermore, education has significant relationship with agricultural adaptation strategies. The study suggests that continuous researches by policy makers, researchers, GOs and NGOs are very essential to exploring and enhancing farmers’ coping and adaptation strategies which may relegate the adverse impacts and vulnerabilities of climate change in the study area.
