At the same time, however, entrepreneurs are often unprepared for cybersecurity needs—and the policymakers, industry, and nonprofit groups that support them also face technological and knowledge constraints in keeping up with their needs. To improve the ability of entrepreneurship research to understand, identify, and ultimately help address cybersecurity challenges, we conduct a literature review on the state of cybersecurity. The research highlights the necessity for additional investigation to aid small businesses in securing their confidential data and client information from cyber threats, thereby preventing the potential shutdown of the business.展开更多

First, we assess whether government-provided cyber threat intelligence (CTI) is helpful in preventing, or responding to, cyber-attacks among small businesses within the U.S. Defense Industrial Base (DIB). Second, we identify ways of improving the effectiveness of government-provided CTI to small businesses within the DIB. Based on a questionnaire-based survey, our findings suggest that government-provided CTI helps businesses within the DIB in preventing, or responding to, cyber-attacks providing a firm is familiar with the CTI. Unfortunately, a large percentage of small firms are not familiar with the government-provided CTI feeds and consequently are not utilizing the CTI. This latter situation is largely due to financial constraints confronting small businesses that prevent firms from having the wherewithal necessary to effectively utilize the government-provided CTI. However, we found a significant positive association between a firm’s familiarity with the government-provided CTI and whether a firm is being periodically reviewed by the Defense Counterintelligence and Security Agency (DCSA) or is compliant with the Cybersecurity Maturity Model Certification (CMMC) program. The findings from our study also show that the participating firms believe that external cyber threats are more likely to be the cause of a future cybersecurity breach than internal cybersecurity threats. Finally, our study found that the portion of the IT budget that small businesses within the DIB spend on cybersecurity-related activities is dependent on the perception that a firm would be the target of an external cyber-attack.展开更多

In particular, business succession in SMEs is a persistent issue. Business succession involves selection of a successor, asset inheritance, transfer of management rights, accumulation of business connections and technology succession, and soforth. This all requires smooth execution of a business succession plan. However, many SMEs do not have a business succession plan, nor are they preparing one. Our task is to explore the reasons these preparations are not being made. Here, the purpose of our research is to get a picture of the status of preparations for business succession in SMEs in China, and the actual circumstances of succession, based on the results of a fact-finding survey of Chinese SMEs, and at the same time bring to the surface the primary factors which influence preparations and plans. The results of the analysis shed light on the status of business succession preparations, successor’s awareness of issues, decision making, and so on. This survey highlights the awareness of business succession among business managers.展开更多

A new gas concentration monitoring system for coal mines is developed on the basis of gas-sensing detection and single-chip control. The monitoring system uses the tin oxide as the main material of N-type semiconductor gas sensors, be- cause it has good sensitive characteristics for the flammable and explosive gas ( such as methane, carbon monoxide). The QM-N5-semiconductor gas sensor is adopted to detect the output values of the resistance under the different gas con- centrations. The system, designedly, takes the AT89C51 digital chip as the core of the circuit processing hardware structure to analyze and judge the input values of the resistance, and then achieve the control and alarm for going beyond the limit of gas concentration. The gas concentration monitoring system has man), advantages including simple in struc- ture, fast response time, stable performance and low cost. Thus, it can be widely used to monitor gas concentration and provide early wamings in small and medium-sized coal mines.展开更多

Under the circumstance of mass entrepreneurship and innovation,a large number of small and medium-sized private enterprises have emerged in all walks of life in China. This paper examines the differences in the definition of entrepreneurial spirit by different scholars,the influence of Chinese entrepreneurship on the development of small and medium-sized private enterprises,the origin of the spirit of private entrepreneurs with Chinese characteristics,and the disadvantages of the spirit of small and medium-sized private entrepreneurs in China. It is necessary to further improve entrepreneurial spirit to contribute to the development of small and medium-sized private enterprises and help China to build the national economic system.展开更多

The study further seeks to determine if IFRS for SMEs can be the solution to better reporting by local SMEs. There has been a growing need for different reporting standards for small firms and big firms over the years due to the unique challenges and attributes they face especially in the area of financial reporting. This research is based on a statistical analysis of questionnaires completed by accountants from SMEs in Swaziland as well as other stakeholders who have a direct or an indirect interest in the financial statements of SMEs. These stakeholders included audit firms and the financial institutions. The sampling rate of 10% was applied across each industry to come up with a sample of 60 SMEs. Furthermore, a 100% sampling rate on the other stakeholders was applied. These were nine financial institutions and eight audit finns. The findings from the study revealed that SMEs in Swaziland are having challenges with the current reporting framework but to some extent, the framework is suitable. Most SMEs are not aware of IFRS for SMEs, therefore the accounting profession in Swaziland (SIA) has a huge role to play in training auditors and accountants in the country. Overall, IFRS for SMEs is applicable in Swaziland.展开更多

Nevertheless, SMEs are facing a lot of problems in the market competition, such as technical backwardness, information lag, lack of talents, etc.. The healthy development of SMEs is very important, whereas, SMEs’ financing is a worldwide problem, and the result of financing game between banks and enterprises depends on a variety of decision-making factors. In this paper, from the point of view of bank, we analyze the diffi culties of external financing of SMEs, and establish a financing game model based on different risk categories, in order to better solve the problems that remain in the process of financing and promote the healthy and sustainable development of SMEs.展开更多

How enterprises can make reasonable decisions on their water environment behavior based on the external environment and their own factors is of great significance for scientifically and effectively designing water environment regulation mechanisms. Based on optimal control theory, this study investigates the design of contractual mechanisms for water environmental regulation for small and medium-sized enterprises. The enterprise is regarded as an independent economic entity that can adopt optimal control strategies to maximize its own interests. Based on the participation of multiple subjects including the government, enterprises, and the public, an optimal control strategy model for enterprises under contractual water environmental regulation is constructed using optimal control theory, and a method for calculating the amount of unit pollutant penalties is derived. The water pollutant treatment cost data of a paper company is selected to conduct empirical numerical analysis on the model. The results show that the increase in the probability of government regulation and public participation, as well as the decrease in local government protection for enterprises, can achieve the same regulatory effect while reducing the number of administrative penalties per unit. Finally, the implementation process of contractual water environmental regulation for small and medium-sized enterprises is designed.展开更多

In this paper, the types of innovation in small business are discussed. Then, a hierarchy comprehensive fuzzy index system evaluating the types of small businesses is proposed. Because of the fuzziness of 15 factors used to analyze the small business, L-R fuzzy number is applied to describe the basic fuzzy state index. Furthermore, the corresponding fuzzy evaluation algorithm is designed. An application example indicated the effects of the methods.展开更多
