Game have become a universal leisure culture for the world. However, not only did the development of the game industry have a positive impact on society, but it also brought about various social problems, such as adversely affecting youth and encouraging criminal acts. In order to minimize these effects, countries around the world operate a game rating system to provide games suitable for age and social values from children and young people to the general public. Since games are new digital content, the limitations of the rating system are still discussed in many studies. Therefore, this study investigates the current status of global game regulation by investigating game rating systems of various countries including Korea. In addition, by comparing and analyzing the game rating system in Korea and the system of other countries, this study suggests a direction to improve our system more appropriately. The results of this study will contribute to securing the effectiveness and standardization of domestic game classification system.

This paper proposes a strategic portfolio model for managing performance of online games. The portfolio matrix is composed of two dimensions: financial performance and non-financial performance. Financial performance is measured by the conventional measure, average revenue per user (ARPU). In terms of non-financial performance, five non-financial key performance indicators (KPIs) that have been widely used in the online game industry are utilized: RU (Register User), VU (Visiting User), TS (Time Spent), ACU (Average Current User), MCU (Maximum Current User). Data envelopment analysis (DEA) is then employed to produce a single performance measure aggregating the five KPIs. DEA is a linear programming model for measuring the relative efficiency of decision making unit (DMUs) with multiple inputs and outputs. This study employs DEA as a tool for multiple criteria decision making (MCDM), in particular, the pure output model without inputs. Combining the two types of performance produces the online game portfolio matrix with four quadrants: Dark Horse, Stop Loss, Jack Pot, Luxury Goods. A case study of 39 online games provided by company 'N' is provided. The proposed portfolio model is expected to be fruitfully used for strategic decision making of online game companies.

This study approaches how newly emerged game companies has implemented strategies for product diversification according to market growth cycle(beginninggrowing-mature) by empirical case study through evolutionary theory and resource based theory approach. At the beginning, online game companies had grown with different strategies(technology based, service based) by initial condition(genre, technological level, user attribute). After market growth, for product diversification, these companies carried out path-dependent alliance strategy(complementary, competitive) depending on resource base(technology capacity, service capacity based). As online game market getting mature, these companies has adapted flexibly in responding to market growth cycle by integrated strategy(naturally selected to mobilize every possible resource capability). By analyzing the alliance strategies pattern of online game companies in newly emerged game industry according to market growth cycle through combination of resource based theory and evolutionary theory, these results suggest that new industrial, theoretical, policy model is required.

The Chinese government has been promoting core industries in accordance with the 'Made in China 2025'. As a result of injecting huge subsidies to develop core industries, a great success has been achieved in the electric vehicle and battery industry, however, the semiconductor industry has almost no performance. This study aims to examine whether the subsidy policy of a developing country helps their own domestic firm to overcome the first mover advantage of an advanced country's firm. From the game theoretical analysis, the results have shown that the subsidy policy of the developing country's government creates the profits shifting effect which arises from the developed country's firm to the developing country's firm. When there exists R&D efficiency gap between the two firms, however, most of these profit shifting effects are offset, which implies that the subsidy policy of developing countries is likely to fail.

Most of the games developed or marketed in the Chinese game market are developed and serviced in foreign countries or are produced in Korea (China) and marketed as services of foreign game companies. If China wants to become the world's game development powerhouse, I think that professional education in multiple methods is the top priority. In particular, I think that a specialized game design department is necessary at a university in China. In this paper, we investigate the game design departments of universities in the United States and the game development powers in South Korea and the Korean game development powers to analyze the educational system of the game design department. Through comparative analysis, a Chinese university finds the necessary elements when establishing a new game design department, and trains advanced game developers in the game field at the Chinese Department of Digital Media Arts. If this study is helpful to the game education in China, it will be studied in the future for the master's program and the doctoral program.

This study first provides a stylized model that captures the essential features of the SC (Social Commerce) business and the competition process. The model focuses on the relationship between key decision issues such as marketing inputs and market value. As more SCs join the industry, they are inevitably faced with fierce competition, which may lead to sharp increase in the total marketing and advertising expenditure. This type of competition may lead the industry away from its optimal development path, and at worst, toward a disruption of the entire industry ecosystem. Such being the case, another goal of this study is to examine the possibility that the ToC (Tragedy of the Commons) may occur in the SC industry. We build game models, each of which assumes homogeneity and heterogeneity of SC providers, respectively, and derive explicit equilibrium solutions from both models. Our basic analysis presents Nash equilibria in both models and shows that SC providers are inevitably faced with fierce competition, which may lead to sharp increase in the total marketing expenses. We also compare the game outcomes with one with a hypothetical social planner who determines the total marketing level that optimizes the entire market value. Then, ToC can be defined to describe the situation where the total marketing efforts exceed the socially optimal level of marketing efforts. In both models, we examine the possibility of the ecosystem disruption and specify the conditions under which ToC may occur. However, the chance of avoiding ToC is higher with heterogeneous players than with homogeneous players. To supplement our analytical results, we develop a simulation model which incorporates a market dynamics based on the gap between actual marketing efforts and socially optimal marketing level. Simulation experiments present some lessons and insights which also confirm out findings from equilibrium analysis. For example, heterogeneity in SC providers alleviates the severity of ToC and makes it faster for survivors to escape from the ToC trap. As a result, the degree of industrial concentration tends to increase, which also explains the 'rich-get-richer' phenomenon observed in some empirical studies on the SC industry. Lastly, based on our analytical and experimental results, we come up with some measures to avoid ToC and overcome the shortcomings intrinsic to the current business model. And further discussions provide strategic implications and policy directions to overcome the possible trap of ToC in this ecosystem, and eventually help the industry to sustainably develop itself toward the next level. To name a few examples of policy measures, regulations on the marketing activities so that the overall marketing expenses cannot go beyond the socially optimal level; institutional guidelines and rules to straightening up the distortions in the way that SC providers view the marketing costs (the current marketing costs are underestimated, thereby encouraging SC providers to increase marketing expenditure); and so on.

The domestic game industry has constantly developed in a short time by concentrating on online games, and keeps growing as a highly added value industry. Also, in the social aspect, it has been seeking various alternatives to place online games as positive and new play culture in the digital era by avoiding negative criticism on game addictiveness. One of important factors in expanding the infrastructure of the game industry and developing it as a type of culture is not simply to develop the existing core genres (on the basis of profits), but to promote the approach of mixture with various contents and of positive functions and thereby enlarge users through various game genres. That is, it is to design games with positive themes and easy immersion by targeting a variety of game users. Such expansion of game design approach is a starting point to develop the infrastructure of the game industry. In the aspect, training professional human resources on the basis of academic and educational process is of significance. Therefore, this work was intended to suggest examples of design approach education based on creativity subject among various subjects with positive functions, and then propose an education process to which Capstone design education contents were applied.

In Korea, the game software and service industry is the core cultural industry from it's significant academic and policy. However, recent growth is slowing down because of increasing competition in the industry. In other words, most of the companies growth have reached limit caused by focusing only on short-term revenue-generating management, Therefore, the game software and service companies are needed to emphasize strategic planning of R&D and product development based on the long-term perspective. The purpose of this analysis is to measure the efficiency of management by data envelopment analysis(DEA), using data from 20 companies in the game software and service industry. Input variances are number of labor, total asset, and total investment and output variances are total sale and enterprise value. The results are followings: First, There was a different efficiency between the companies in the game software and service industry. The eight companies was inefficiency. Second, six inefficiency companies were excessive number of the employees and investment assets. third, four companies were CRS, five companies were IRS and eleven companies were DRS. From the result, five companies have to increase the scale of input variance and eleven companies also have to improve efficiency of input variance.

Recently, to make game gotten out of negative perception of game addiction and gradually established as an immersion-centric and ositive and new game culture of the digital era from a culture perspective, the necessity of development of game composed of various materials has been emerging. In other words, the important part to make the environment of game industry which is growing into a higher value-added business expanded in a short space of time as the base culture together with the public in cultural aspects is the development of game material which enables more various objects to approach besides the development of material focused on profit. Above all things, it is the easily accessible material through fusion sith the diverse contents by using elements of interaction, function, system which game itself has. In this connection, this study suggested design approach process ti fuse the material of positive function into game and also proposed the development case ay each level.
