Robots are widely used in industrial manufacturing and service industries around the world. However, most of the previous studies on industrial robots use data at the national or industry level in the context of developed countries. This study examines the impact of imported industrial robots on firm innovation at the firm level in China.

Drawing on a large dataset of more than three million records in China, including non-publicly traded small and medium firms, the authors adopt a difference-in-differences method to investigate the impact and channels of industrial robots on firm innovation.

The authors find that the application of industrial robots increases firm innovation. Two possible channels are identified through which robots promote innovation: alleviation of financial constraints and the improvement of human capital. Further analysis shows that the effect of robots on innovation is more pronounced for firms that are highly dependent on external financing, belong to high-tech industries, import high-end robots, have insufficient supply of skilled labor and private firms (non-SOEs). The authors also find that industrial robots increase the firms' innovation quality and the marginal contribution of innovation to firms' total factor productivity.

This study provides big data evidence of the unintended positive consequences of industrial robots on firm innovation. The results are helpful to clarify the controversy of industrial robots. It also has important implications for government industrial policy making, firm innovation and human resource management.

The purpose of this paper is to explore the effects of competitive pressure on financial statements’ comparability (comparability) by analyzing various dimensions of competition.

The authors study the effect of competition on comparability using the comparability measure of De Franco et al. (2011) and various proxies for competition, competition from existing/potential rivals and non-price competition (NPC).

This study documents that competition is positively associated with comparability, and this effect is more (less) pronounced for industry followers (leaders). The authors also document that competition from existing rivals enhances comparability, but competition from potential entrants does not. Moreover, NPC is also a significant determinant of comparability. Furthermore, the competition from existing/potential rivals plays no significant role in the production of comparable financial statements in state-owned enterprises. The results are robust to alternative measures of comparability and methodological approaches.

This study is the first empirical study that documents a new channel (comparability) through which competition affects financial statements. The findings support the argument that competitive pressure acts as a governance mechanism, disciplines management and increases comparability leading to lower information asymmetry (governance view). However, the findings contest the argument that higher competition motivates managers to withhold information (proprietary cost hypothesis). By examining the effect of state ownership, this study might also help to characterize the effects of changes in corporate objectives on managerial decisions related to financial reporting.

The conventional textile dyeing process requires various operational characteristics, and determining the most reliable factor in dyeing performance has always been a challenge for the textile industry. Thus, the present paper aimed to evaluate the process sensitivity of C. I. Reactive Blue 194 dyeing of cotton fabric using a statistical technique.

An L₂₇ orthogonal array-based Taguchi's methodology was used with six parameters and three levels of each parameter. The signal-to-noise (S/N) ratio and analysis of variance were studied using total fixation efficiency (T%) as the response of the process sensitivity.

Results showed that dyebath pH was the most influential factor on the process and total fixation efficiency (p-value = 0.00 and contribution percentage 45.03%), followed by dye-fixing temperature, dye mass, electrolyte concentration, dye-fixing time and material to liquor ratio.

Overall this study provides a foundation for the determination of dyeing process sensitivity that will be useful in textile industries toward further development.

This study searches for sentimental herding in Borsa Istanbul (BIST) during the last decade using a state-space model employing cross-section standard deviations of systematic risk (Beta). It has been found that herding toward the market in the BIST-100 is both statistically significant and persistent independently from market fundamentals such as the volatility of returns and the levels of market returns. Herding trends over the sample period indicate that the financial crisis in 2000–2001 appeared to bring about sentimental herding in BIST which was followed by a calm period during which investors turned to fundamentals. Thereafter, we observe a volatile adverse herding pattern till the end of 2011 due to the confusing environment caused by the internal and external events.

The primary aim of this study is to examine the decision-making process of a reverse supply chain within a cooperative-competitive environment, with a particular emphasis on the incorporation of Internet of Things (IoT) technology in the recycling process.

The impact of IoT on recycling effectiveness, RF (refurbished) product demand and remanufacturing expenses is analyzed. The game-theoretic models are constructed to incorporate the co-competitive relationship between a IR (Internet Recycler) and a remanufacturer, with specific attention paid to the IR's application of IoT technology.

The results indicate that the use of IoT reduces the costs associated with remanufacturing, leading to an increase in the transfer price of pre-owned items procured from IRs. The efficacy of the reverse supply chain depends not only on its cost-saving capabilities but also on consumer preferences toward RF and remanufactured (RM) items.

IoT technology can benefit Internet recycling and remanufacturing by enhancing transparency, quality monitoring and automation of processes. It can also help reduce operating costs, improve customer engagement and incentivize cooperation between organizations.

This study examined the strategic decision-making processes in the context of cooperation and competition between IR and remanufacturers. In addition, this research makes a valuable contribution to the literature by elucidating the optimal conditions for the effective implementation of Internet of Things (IoT) technology in recycling operations.

The blade profile and its geometrical features play an important role in the separation of the boundary layer on the blade. Modifying the blade geometry, which might lead to the delay or elimination of the flow separation, can be considered as a passive flow control methodology. This study aims to find a novel and inexpensive way to reduce loss with appropriate modifications on the leading edge of the turbine blade.

Three types of wave leading edges were designed with different wavelengths and amplitudes. The selected numbers for the wave characteristics were based on the best results of previous studies. Models with appropriate and independent meshing have been simulated and studied by a commercial software. The distribution of the loss at different planes and mid-plane velocity vectors were shown. The mass flow average of loss at different incidence angles was calculated for the reference blade and modified ones for the sake of comparison.

The results show that in all three types of modified blades compared to the reference blade, the elimination of flow separation is observed and therefore the reduction of loss at the critical incidence angle of I = –15°. As the amplitude of the wave increased, the amount of loss growing up, while the increase in wavelength caused the loss to decrease.

The results of the present numerical analysis were validated by the laboratory results of the reference blade. The experimental study of modified blades can be used to quantify numerical solutions.

This paper examines how the level of low-carbon awareness (LCA) affects the remanufacturing strategy in a supply chain with an original equipment manufacturer (OEM) and an independent remanufacturer (IR) competing with each other.

Game theory and operations optimization.

The studies analytically characterize the threshold levels of the LCA in response to which the OEM and the IR will change their remanufacturing strategies from no remanufacturing to partial remanufacturing and then to full remanufacturing. In addition, the studies reveal that as compared with the OEM, the IR has more flexibility in terms of the market entry to remanufacturing with the level of LCA increasing. With the extended studies, it is exhibited that the above findings are robust to a good extent.

It can provide decision support for remanufacturing enterprises.

Under the carbon regulation mechanism, managing operational strategies is a challenging task. Green innovation is introduced into a hybrid system of manufacturing and remanufacturing to handle the carbon emission constraints in a dynamic market environment. This paper aims to investigate the joint dynamic green innovation policy and pricing strategies in a hybrid manufacturing and remanufacturing system.

This paper first considers a monopolistic manufacturer who offers brand-new products and remanufactured items at the same price to consumers. Subsequently, the authors extend their analyses to distinct pricing strategies for both newly manufactured products and refurnished ones in such a hybrid system. Two different cases are considered: a loose carbon emission constraint and a binding carbon emission constraint. By solving the dynamic optimization problem, the differential game and Pontryagin’s maximum principle are used to obtain the joint green innovation and pricing strategies.

The retail price first increases then declines over a single period. The green innovation diminishes in the same pricing decision model, while it first increases then declines in a distinct pricing decision model over a single planning horizon. The green innovation investment as well as the retail price are discouraged by an emission cap and recycling fraction. The distinct retail price fluctuates violently, and they are, in descending order of the highest peak price as follows: the newly manufactured product, the same pricing product and the repaired product. Carbon emission caps that are either too high or too low decrease the revenue of the manufacturer. A small emission constraint margin benefits the manufacturer. The recycling policy, as well as other parameters, affects whether the hybrid system attains the carbon emission constraint or not, which suggests that the recycling policy is complementary to the carbon emission constraint mechanism in the hybrid system.

These results offer managerial implications to the hybrid system in terms of green innovation, pricing strategies and recycling policy.

This paper is among the first papers to research the joint dynamic green innovation policy and pricing strategies with/without a carbon emission constraint in a hybrid manufacturing and remanufacturing system with a differential game. Moreover, this paper presents a potential way of investigating other common resource constraints by a differential game in a manufacturing/remanufacturing system or closed loop supply chain.

This paper aims to propose a two-period model, including an original manufacturer, a retailer and a third-party remanufacturer, in which the products manufactured by the original manufacturer are patent-protected and the remanufacturing degree of remanufactured products influences the purchasing decisions of consumers.

This paper analyzes the decisions of the original manufacturer, the retailer and the third-party remanufacturer of two periods, using Stackelberg game and obtains the equilibrium solutions of the three parties.

The study finds that consumers’ focus degree to the remanufacturing degree has a negative correlation with the equilibrium unit patent-licensing fee, the retail price of remanufactured products, the remanufacturing degree of remanufactured products and the wholesale price of new products in the first period, but has a positive correlation with the retail price of new products in the second period.

(1) Consumers’ focus degree to the remanufacturing degree has a negative correlation with the equilibrium unit patent-licensing fee, the retail price of remanufactured products, the remanufacturing degree of remanufactured products and the wholesale price of new products in the first period, but has a positive correlation with the retail price of new products in the second period. (2) The remanufacturing action efficiency of the third-party remanufacturer has a positive correlation with the equilibrium unit patent-licensing fee, the retail price of remanufactured products, the remanufacturing degree of remanufactured products and the wholesale and retail prices of new products in the second period.

The purpose of this paper is to assess critically the political challenges facing Hong Kong’s “one country, two systems” policy following the Umbrella Movement and to evaluate the territory’s democratic and autonomous future.

A critical, contextual, and analytical approach has been adopted to evaluate the problems and prospects for post-Umbrella Movement Hong Kong.

The contradictions embedded in the “one country, two systems” policy have become apparent since the Umbrella Movement arose and Hong Kong’s political and democratic future is as problematic as its prospects are uncertain, though the possibility of some rapprochement between Hong Kong and Beijing should not be ruled out completely.

The critical evaluation offered by this paper is no scientific prediction. Social scientific analysis of this kind is suggestive rather than definitive. The informed discussion offered by this paper will help readers to better understand the strengths and weaknesses inherent in Beijing’s “one country, two systems” policy and the tortuous process of democratization in Hong Kong. The conclusion drawn in the paper points to a possible way out of the political impasse that is facing post-Umbrella Movement Hong Kong.

This paper is a pioneering study of the most important political conflict between Beijing and Hong Kong since 1997, the conclusion of which may have important political and policy implications for both China and Hong Kong.
