Different from Marx's analysis of the dialectical relationship between the production and realization of surplus value, the Okishio theorem only shows one aspect of the contradictory movement of the total social capital, that is, the reverse effect of the realization of surplus value on the production of surplus value.

The production of surplus value and the realization of surplus value are simplified into one process. This simplification eliminates the contradiction between the production and realization of surplus value, and the antagonistic contradiction between accumulation and consumption and the antagonistic production-distribution relationship in capitalist society are naturally covered up.

Therefore, it cannot explain the actual expansion way of the falling general rate of profit as the historical development law of capitalism. Nevertheless, it should be noted that the Okishio theorem places the analysis of the general rate of profit back into the social reproduction model with department equilibrium, which points out the significance of wage income to the realization of surplus value and outlines the macro mechanism of the realization of surplus value reacting to the production of surplus value. It also strongly promotes the research progress of the law that the profit rate tends to decline.

The mistake of the Okishio theorem is that the exchange process in the labor market forms the real wage rate. It determines the production price of wage goods, which thereby determines that the production price of capital goods and general rate of profit, the production of surplus value and realization of surplus value are simplified into the same process, and only the value that can be realized is the real value.

Starting from the theoretical mechanism of profit sharing between finance and the real economy, this paper reviews and analyzes the profitability of China's banking industry and makes a horizontal comparison with the banking industry of the United States, Japan, and Germany.

Based on the panel threshold model, it is found that there is a dual-threshold asymmetric effect between banking profit and the growth of real economy. When the net profit rate of the banking industry is lower than 0.491%, the increase in banking profitability will inhibit the growth of real economy due to profit grabbing; when the rate falls within the range of 0.491–0.801%, the increase in bank profitability is conducive to the growth of real economy.

Finance and the real economy are in the most comfortable symbiotic state; when the rate is higher than 0.801%, the continued increase in bank profitability will weaken the promotion effect of finance on the real economy, but bank profitability and the growth of real economy are still in a symbiotic state of positive promotion.

The promotion effect of China's bank profitability to the growth of real economy has shifted from the suboptimal state to the optimal range as a whole, which is attributed to the strong deleveraging and strict supervision of the Chinese government after 2016, the timely and decisive “stepping on the brakes”, pulling the financial sector back from the “illusion” caused by “self-circulated” profits and preventing it from harming the real economy.

The United States (US) sugar program protects domestic sugar farmers from unrestricted imports of heavily-subsidized global sugar. Sugar-using firms (SUFs) criticize that program for causing US sugar prices to be higher than world sugar prices. This study examines the financial performance of publicly traded SUFs to determine if they are performing at an economic disadvantage in terms of accounting profitability, risk and economic profitability compared to other industries.

Firm-level financial accounting and market data from 2010 to 2019 were utilized to construct financial metrics for publicly traded SUFs, agribusinesses and general US firms. These financial metrics were analyzed to determine how SUFs compare to their agribusiness peer group and general US companies. The comprehensive financial analysis in this study covers: (1) accounting profit rates, (2) drivers of profitability, (3) economic profit rates, (4) trend analysis and (5) peer comparisons. Quantile regression analysis and Wilcoxon–Mann–Whitney statistics are employed for statistical comparisons.

Regarding various profitability and risk measures, SUFs outperform their agribusiness peers and the general benchmark of all US firms in terms of accounting profit rates, risk levels and economic profit rates. Furthermore, compared to other US industries using the 17 French and Fama classifications, SUFs have the highest return on investment and economic profit rate―measured by the Economic Value Added® margin―and the second-lowest opportunity cost of capital, measured by the weighted average cost of capital.

This study finds nothing to suggest that the US sugar program hinders the financial success of SUFs, contrary to recent claims by sugar-using firms. Notably in this analysis is the evaluation of economic profit rates and a series of robustness techniques.

There exist long-term fluctuations in the process of capital accumulation. The economic long wave is an essential part of research into non-mainstream western economics. After the Second World War, the capitalist world experienced the fourth long wave of expansion and then entered into a downward phase of the long wave in the 1970s. Regarding to whether a new long wave of expansion took place in the 1980s, left-wing scholars hold different viewpoints. The purpose of this paper is to focus on this issue.

First, based on the review of the long wave history, this paper discusses three kinds of long wave theories with significant influence and puts forward the theoretical framework of analyzing the long wave of capitalist economy. Next, under the guidance of this theoretical framework and in combination with the actual development and evolution of the capitalist economy, the issue of whether the fifth long wave of the capitalist economy began to emerge in the 1980s is discussed deeply.

This paper argues that, from the early 1980s to 2007, the US-dominated developed countries experienced a new long wave of expansion driven by the information technology revolution, the adjustment of the neoliberalism system and the economic globalization. However, the financial-economic crisis of 2008–2009 led to a new phase of long wave downswing.

This paper does not agree with the single-factor analysis of the intrinsic formation mechanism of economic long wave and sticks to the multi-factor analysis centering on the fluctuation of accumulation rate. It is pointed out that the evolution of the long wave of capitalist economy depends on the combined influence of technology, institutions and market. The study of the long wave of the economy will help us to correctly understand the historical stage and characteristics of the current world capitalist economy in the long-term fluctuations, so that we can make an appropriate and positive response.

This paper aims to understand the issue of interest rate benchmarking in Islamic financial institutions (IFIs) from a macro-economic perspective and assessing the relevance of creating a Sharīʿah-compliant profit rate benchmark to solve this issue. This paper also aims at suggesting an Islamic alternative that will handle both the negative economic impact on IFIs as well as on their financial performance.

The paper is based on literature review of conventional finance and Islamic finance theories to construct a theoretical model to assess the impact of interest rate benchmarking on the ability of IFIs to achieve the objectives of the Islamic economy.

The macro-economic perspective concludes that conceiving a profit rate benchmark for the Islamic finance industry is not relevant to raising the Sharīʿah credibility of the industry. Indeed, several adjustments need to be introduced in terms of the business model.

The recommendations of this paper require the involvement of financial authorities and governments for their implementation. Indeed, the adjustments require a macro-economic review.

The paper considers a profit rate benchmark irrelevant and inefficient. Instead, it suggests the necessary adjustments in terms of business model and economic approach for IFIs to achieve their objectives.

The paper considers zakat implementation and the adjustment of IFIs as the real path to implement a fair wealth distribution in the society.

The creation of a profit rate benchmark has always been the only solution for the pricing issue in IFIs. This paper challenges this idea and tries to give a deeper understanding of the situation.

The purpose of this paper is to examine the correlation between firm size, growth and profitability along with other firm-specific variables (like leverage, competition and asset tangibility), macroeconomic variable (like GDP growth-business cycle) and stock market development variable (like MCR).

Using the COMPUSTAT Global database this work uses panel dynamic fixed effects model for nearly 12,001 unique non-financial listed and active firms from 1995 to 2016 for 12 industrial and emerging Asia–Pacific economies. This interrelationship was also examined for small, medium and large size companies classified based on three alternate measures such as total assets, net sales and MCR of firms.

The persistence of profits coefficient was found to be positive and modest. There is evidence of a negative size-profitability and positive growth-profitability relationship suggesting that initially profitability increases with the growth of the firm but eventually, overtime, gains in profit rates reduce, as size increases indicting that large size breeds inefficiency. The relationship between firm's leverage ratio and its asset tangibility is found to be negative with profitability. The business cycle and stock market development variables suggest a positive relationship with the profitability of firms. However, the significance of estimated coefficients was mixed and varied among different selected Asia–Pacific economies.

The study has economic implications on issues such as industrial concentration, risk and optimum size of firms for practicing managers of modern enterprise in emerging markets.

The analysis of the relationship between the firm size, growth and profitability is uniquely determined under a dynamic panel fixed effects framework using firm-specific variables along with macroeconomic and financial development determinants of profitability. This relationship is estimated for a large and new data set of 12 industrial and emerging Asia–Pacific economies.

本研究擬探討公司的規模、成長和盈利能力之間的關係， 同時亦涵蓋公司特有的其它變量 （如愩杆作用， 競爭和資產的有形性）， 宏觀經濟變量 （如國內生產總值增長與景氣之循環）， 以及股市發展變量 (如MCR) 。

本研究以COMPUSTAT 全球資料庫、使用動態面板固定效應模型，涵蓋幾近12001間獨特的、非金融上市及活躍的公司、覆蓋期由1995年至2016年，涉及12個工業及新興的亞太經濟體。這相互關係分析研究亦於大、中及小型企業內進行，而這些企業就規模方面的分類是基於三個交替的測量而釐定的，如總資產、銷售淨額、以及企業的MCR。

研究發現、利潤係數的持續性是正且適中不強的。有證據顯示、規模的大小與盈利能力是負相關的，而增長與盈利能力則為正相關；這暗示盈利能力初時會因企業的成長而增強，但隨著時間的推移最终當規模增大、利潤率的增長會下降，這提示我們：大的規模會導致效率低下。企業的杠桿比率與其資產有形性的關聯被發現與盈利能力成負相關。經濟週期及股市發展變量暗示與企業的盈利能力之關聯為正相關。唯估計係數的意義會因被挑選之各個不同亞太經濟體而有異和不統一的。

本研究對在新興市場的現代企業內工作的業務經理有其實際作用，因研究為他們在業務問題如產業集中度、危機、公司的最佳規模等問題上提供了經濟方面的啟示。

本研究分析公司規模、成長與其盈利能力的關係時，獨特之處是採用了動態面板固定效應模型，並於應用盈利能力的宏觀經濟和金融發展的決定因素的同時，也使用了企業特有的變量。而這關係的分析研究涵蓋12個工業及新興的亞太經濟體的龐大且新的數據集。

In the current literature, there is little systematic research on the relationship among adjustment of the income distribution, change in economic structure and improvement of macroeconomic efficiency.

This paper expands Marx's reproduction schema into the “Marx–Sraffa” three-department structure table comprising fixed capital, general means of production and means of consumption and employs China's input–output table from 1987 to 2015 to portray the relationship between income distribution and macroeconomic efficiency under investment-driven growth.

This paper calculates the wage–profit curve of China's economy and evaluates the space of macroeconomic efficiency improvement in China based on the deviation between actual and potential income distribution structure.

The results show that there is a downward trend of the profit rate, which meets Marx's theoretical prediction, and the decline in the profit rate is mainly attributed to an increase in the organic composition of capital arising from the rapid growth of fixed capital investment under extended growth. The analysis of macroeconomic efficiency shows that the space for improving macroeconomic efficiency is extremely limited under traditional growth pattern and that China must transform its economic development pattern and foster new economic growth drivers.

This paper aims to examine the distributional differences of Islamic bank financing responses to financing rate across bank-specific characteristics in dual banking system. The study also aims to provide understanding of how efficiently Islamic banks perform their roles as suppliers of capital for businesses and entrepreneurs.

The study uses panel regression methodology covering all Islamic banks in Malaysia. The study estimates the benchmark model for Islamic bank financing with respect to bank characteristics and monetary policy.

The evidence suggests that bank-specific characteristics are important in determining Islamic financing behaviour. The Islamic financing behaviour is consistent with conventional lending behaviour that the Islamic bank financing operates depending on the level of bank size, liquidity and capital. There is no significant difference between Islamic bank financing and conventional bank lending behaviour with respect to changes in monetary policy.

Many problems and challenges relating to Islamic financing instruments, financial markets and regulations must be addressed and resolved. In practice, it would be a good idea if Islamic banks move away from developing debt-based instruments and concentrate more efforts to develop profit and loss sharing instruments.

The Internet of Things (IoT) is used in the fresh agricultural product (FAP) supply chain, which can be coordinated through a revenue-sharing contract. The purpose of this paper is to make the three-level supply chain coordinate in IoT by considering the influence of FAP on market demand and costs of controlling freshness on the road.

A three-level FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT is regarded as the research object. This study improves the revenue-sharing contract, determines the optimal solution when the supply chain achieves maximum profit in three types of decision-making situations, and develops the profit distribution model based on the improved revenue-sharing contract to coordinate the supply chain.

The improved revenue-sharing contract can coordinate the FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT, as well as benefit all enterprises in the supply chain.

Resource utilization rate can be improved after coordinating the entire supply chain. Moreover, loss in the circulation process is reduced, and the circulation efficiency of FAPs is improved because of the application of IoT. The validity of the model is verified through a case analysis.

This study is different from other research in terms of the combination of supply chain coordination, FAPs, and radio frequency identification application in IoT.
