Evolution and Governance of the Structure of Marine Economic Networks in China’s Coastal Areas: Based on Sea-related A-share Listed Companies

Data on discrete,isolated attributes of the marine economy are often used in traditional marine economic research.However,as the focus of urban research shifts from internal static attributes to external dynamic linkages,the importance of marine economic net-work research is beginning to emerge.The construction of the marine economic network in China’s coastal areas is necessary to change the flow of land and sea resources and optimize regional marine economic development.Employing data from headquarters and branches of sea-related A-share listed enterprises to construct the marine economic network in China,we use social network analysis(SNA)to discuss the characteristics of its evolution as of 2010,2015,and 2020 and its governance.The following results were obtained.1)In terms of topological characteristics,the scale of the marine economic network in China’s coastal areas has accelerated and expan-ded,and the connections have become increasingly close;thus,this development has complex network characteristics.2)In terms of spatial structure,the intensity of the connection fluctuates and does not form stable development support;the group structure gradually becomes clear,but the overall pattern is fragmented;there are spatial differences in marine economic agglomeration radiation;the radi-ation effect of the eastern marine economic circle is obvious;and the polarization effect of northern and southern marine economic circles is significant.On this basis,we construct a framework for the governance of a marine economic network with the market,the government,and industry as the three governing bodies.By clarifying the driving factors and building objectives of marine economic network construction,this study aims to foster the high-quality development of China’s marine economy.

The Value of Saudi Arabia Industrial Firms Between the Modigliani-Miller＇s and Gordon＇s Models： An Empirical Study on Cement Companies in Saudi Arabia

The most important target of the financial management is to develop the values of the foundation and develop the wealth of shareholders （wealth of the owners）, which is the primary target of the qualified and successful financial management. This target, developing the value of the foundation, depends on the total profit that could be achieved by the company and counting the profit per share, but undoubtedly, the financial management should consider the other targets such as social responsibility and exchange between risk and revenue and others. This research, with its both theoretical and practical aspects, aims at illuminating the value of some foundations in Saudi Arabia, which are already registered in the stock market, by comparing the value of each foundation using two models namely the model of Modigliani-Miller （M＆M） and the model of Gordon. In spite of the difficulties found in the usage of both models, especially Gordon＇s model, we will use both of them to explain the aspects of imperfection in each model. This research will depend on a sample of Sandi industrial companies by getting financial data of these companies over a past decade and the usage of these data, in other words, to measure the value of Saudi companies against the market.

Application of modified banker’s algorithm in FMS deadlock problem

Presents a method for deadlock avoidance algorithm used in Flexible Manufacturing System(FMS). This method is an improvement of the Banker algorithm. The Banker algorithm is commonly used in the Operating System (OS), but some improvements will have to be made on the algorithm if this algorithm is used in FMS. The difference between the process in operating system and the job in the FMS is fully discussed. Based on this difference, the improvement is made. In order to improve the algorithm, formal methods are adopted to the manufacturing systems. The simulation model is translated into a format suitable for model checking. That is, the model is written into PROMELA, the input language of the popular model checker SPIN. After that, SPIN is used to verify that the model does not have deadlock. This algorithm proves to be highly effective in practice.

Elementary Siphons of Petri Nets and Deadlock Control in FMS

For responsiveness, in the Petri nets theory framework deadlock prevention policies based elementary siphons control are often utilized to deal with deadlocks caused by the sharing of resources in flexible manufacturing system (FMS) which is developing the theory of efficient strict minimal siphons of an S3PR. Analyzer of Petri net models and their P-invariant analysis, and deadlock control are presented as tools for modelling, efficiency structure analysis, control, and investigation of the FMSs when different policies can be implemented for the deadlock prevention. We are to show an effective deadlock prevention policy of a special class of Petri nets namely elementary siphons. As well, both structural analysis and reachability graph analysis and simulation are used for analysis and control of Petri nets. This work is successfully applied Petri nets to deadlock analysis using the concept of elementary siphons, for design of supervisors of some supervisory control problems of FMS and simulation of Petri net tool with MATLAB.

Study on Influencing Factors of Capital Structure of Energy Listed Companies

Based on the determinative factors school of capital structure theory, this paper uses the data of 35 Chinese energy listed companies from 2000 to 2003, and adopts multi-variable regression method to make an empirical study of the influencing factors of their capital structure. The results indicate that the factors of size, income volatility, and the concentration of owner’s equity have positive relation with the capital structure, while the relation between profit- ability and capital structure is negative. It is also found that the influencing of growth and secured asset on the capital structure are relatively insignificant.

Chinese Oil Companies＇ Overseas Cooperation in 2016

The paper analyzed the development and features of China's oil companies' overseas business in 2016.Despite the plummeting crude price and a weak global economy,these companies managed to do well in foreign countries.They steadily increased their shares of oil and gas in overseas oil and gas projects with their distinctive and unique ways:the three state-owned oil companies had focused on the countries involved in the One-BeltOne-Road Initiative,and others had been stressed more on international cooperation in a broader sense and areas.The small-and middle-scale companies had been matured and grew during the process.The central and local governments also played indispensable roles by providing need support for the cooperations.

Analysing on External Environment and Industrial Competition of High-Tech Companies—Using Tesla as an Example

As the impact of the global energy crisis deepens,traditional oil resources are exhausted,and the harm caused by air pollution and rising global temperatures is increasingly severe;the government and automobile enterprises generally believe that energy saving and emission reduction is the future technology development direction of the automobile industry.The main direction of the attack is the general trend of new energy vehicles to replace traditional vehicles.As a leader in new energy pure electric vehicles,Tesla Motors has created a new concept of using the Internet for manufacturing cars and opened up a new brand segment of the automobile market.This paper mainly uses the PEST analysis model and Porter’s Five Forces analysis model to understand the essence of Tesla is not a pure electric vehicle manufacturer,but a high-tech innovation driver at the forefront of the world.Based on the PEST model analysis,Tesla’s development is still at the right time and place despite the impact of COVID-19.From Porter’s Five Forces model,Tesla has higher bargaining power and a strong dominant position with upstream suppliers and service providers.Tesla has a first-mover advantage due to its customers’weak bargaining power,which lets Tesla’s leading position in the industry cannot be surpassed in the short term.
