Based on the CDM model, this paper empirically examines the links of R&D, innovation, and labor productivity using Korean Community Innovation Survey (KCIS) for manufacturing firms over the period 2013 to 2015. Estimating the model, I attempt to alleviate two major econometric problems such as endogeneity for the variables and sample selection biases caused by distribution problems of R&D spending and technological innovations. To do this, I control the former bias by employing sequential instrumental variable estimation procedures, and the latter by using both the Generalized Tobit model and the bivariate probit estimation technique. Main empirical findings in the paper can be summarized as follows. First of all, this paper found that the separate estimation of the structural CDM model should lead to biased results due to ignoring sample selection and endogeneity problems. This evidence confirms validity of using botht the bivariate probit model and the type II Tobit model. Second, the results show that R&D expenditure should be positively associated with enhancement of product innovation, rather than process innovation. This implies that government R&D support can have a stronger effect on encouraging product innovation through an increase in R&D investment in SMEs. Third, the innovation protection methods, both legal and strategic, are found to have a positive effect on R&D investment but no effect on R&D intensity. In the innovation output models, on the other hand, only strategic protection method can have a positive effect on both product and process innovations. Fourth, the firm size proxied by the number of workers is found to be negatively related to the R&D investment. As the size of firms grows, the probability of R&D investment is higher, but per worker R&D investment is smaller. This evidence supports Scherer's hypothesis that innovation activities are more active of small-medium firms in the competitive markets, rather than in the monopoly market suggested by Schumpeter. Fifth, the results show that information flow from suppliers and customers plays an important role as source of knowledge for invention and innovation. In the knowledge production function or the innovation output model, the flow has a positive effect on both the product and process innovation. However, information flow from competitors is found to affect process innovation, but it is not useful to develop new products. Next, the estimated coefficients for government financial support are found to be statistically significant in both the R&D investment decision and the R&D intensity models. This implies that the government financial support can have crowding-in effects on R&D investment, rather than crowding-out effects, and thus it could lead to an enhancement of R&D investment in SMEs. Finally, the results show that the estimated coefficients of the predicted values for product innovation are statistically significant in the labor productivity model, implying that product innovation should have a positive effect on labor productivity and thus eventually affect economic growth positively. This results also confirms existence of endogeneity problem with product innovation, not with process innovation.

The present study adopts the cobweb theory as a basic model to capture the industrial dynamics in the agriculture industry of Korea. We examine the validity of the theory by analyzing the archival data of agricultural products. Specifically, we pay attention to Korean farmers' gamesmanship behavior as a characteristic of rational supply chain participants and try to test the conventional wisdom that the Korean government's intervention in the agricultural market has stimulated farmers' opportunistic behavior for producing an excessive level of produces. According to the panel data analysis results, an increase in the agricultural commodity's price in the recent past and farmers' production quantity have a significant positive association. Yet, the government's subsidy alone does not seem to induce Korean farmers' opportunistic behavior. In addition, we show the interaction between the change in prices and the government's purchase quantity. That is, if the market prices are expected to rise in anticipation that the government may purchase their farm surpluses at better prices farmers make a more aggressive decision on the production for the next season. This outcome may contradict the fundamental goal of the government subsidy, which is the stabilization of the market. Therefore, when the government implements a certain policy, it should consider market dynamics in which the policy affects the policy beneficiaries' behavior.

Business digitalization has had pervasive effects on organizations, industry structures and the economy as a whole. Business digitalization is being emphasized as an innovation strategy on the supply chain and the burden on the competitive advantage, which must adapt to business digitalization, is the cause of the company's difficulties in dealing with environmental changes. Therefore, the purpose of this study is to empirically analyze the effect of supply chain dynamic capabilities that enable smooth exchange of resources and information in the front and rear of the supply chain and interaction with partnership firms on business digitalization performance. To this end, data was collected through online surveys targeting companies participating in manufacturing and supply chain that are implementing digitalization. Specifically, we selected electronics, automobiles, pharmaceuticals, machinery, etc., which are digitalization applied to Seoul/Gyeonggi, Daejeon and Gyeonsang regions. In order to minimize common method bias, this survey was conducted by clarifying the concepts such as “supply chain dynamic capability” and “business digitalization” as measured variables through a preliminary survey. In addition, in order to minimize non-response convenience, it was attempted to increase the validity of the analysis results by excluding them from analysis. As a result, we found that supply chain dynamic capabilities had a positive and significant effect on business digitalization performance. Also, although the effect of business digitalization performance on supply chain performance has been shown to have a positive and significant effect, it prove that supply chain performance decreases as external opportunities increase among business digitalization performance. Therefore, by focusing on the dynamic capabilities of the supply chain, companies can increase their understanding of the introduction of new technologies and increase the operational efficiency of the supply chain environment. we identified that the network due to convergence with digital technology can be linked to the occurrence of security incidents for various information such as market demand, inventory, and quality in the supply chain.

This study empirically analyzes the effects of the use of non-regular workers and indirect workers on the financial performance of companies in South Korea. The study uses data from the Workplace Panel Survey which consists of representative workplaces in South Korea. More specifically, this study extends the time series data to the most recent 2017 WPS wave, and uses function estimation methodology of Olley and Pakes(1996) to control endogeniety which usually occurs in the analysis of business productivity. Through the estimation process, this study is expected to contribute to providing the theoretical and empirical foundations and policy implications for setting the policy basis for the rigidity of the labor market and the level of employment protection. We found that the corporate performance from using non-regular workers differs according to the size of the employees, and the corporate productivity measured by added value per person has a linear negative relationship with the proportion of non-regular workers and indirect employment, but also a non-linear inverse U-shaped relationship in large companies. The result shows its significance in both analysis targeting all industries and analysis limited to manufacturing industries. It implies that the added value per person increases up to a certain proportion but decreases after the critical point when companies utilize non-regular and indirect employment. This leads to inference that the effect of corporate productivity of the use of non-regular workers can be expressed differently according to the distribution of the proportion of the use of non-regular workers. However, the result did not appear to be significant in terms of per capita operating income and sales, and it did not have a significant effect on businesses with less than 300 employees. It is likely to be due to the difference in investment methods for productivity improvement between small and large-scale businesses. Other than the use of non-regular and indirect employment, education and training expenditure per person, research expenditure, overseas market ratio also seem to affect corporate productivity measured by revenue, operating profit, and added value per employee. We found the education/training expenditure per person and the size of the company increased sales and operating profit per person throughout the analysis in general, but it did not have a significant relationship with added value per person. This study focuses on the corporate performance of non-regular and indirect employment, but as shown in the analysis, the financial performance of a company is influenced by various factors in addition to the difference in the proportion of employment types. The sales per person appears to be affected not only by the ratio of the use of non-regular workers, but also total number of employees, union status, training costs per person, and subcontracting transactions. In addition, the proportion of non-regular and indirect employment utilization appears to have different effects depending on the size of the employees, suggesting that the proportion of non-regular workers in companies should not be considered as a single factor for estimating or forecasting corporate performance. In addition, considering that variables such as entrepreneurship and organizational culture that cannot be observed in the survey data can also have a significant impact on corporate performance, it needs to be careful to put excessive weight only on employment decisions in improving corporate financial performance and productivity. In determining the level of employment protection and legislation, the government would be better not to focus on the use of non-regular workers, i.e., at what level to determine the level of quantitative use. Efforts, however, should be made to bring more balanced labor flexibility in terms of employment quality, such as the working conditions and environment of workers. The limitations of this study are as follows. The Workplace Panel Survey used in this study consists of companies with 30 or more employees as a population, and companies with less than 30 employees are excluded from the sample. In future studies, it is necessary to conduct an analysis through data reflecting more small businesses. Therefore, it is possible that the proportion of non-regular workers shown in the analysis data was observed to be lower than in reality, and this may cause bias in estimating the effect of using non-regular and indirect workers on corporate productivity estimated in this study. In addition, the Workplace Panel Survey includes indefinite contract workers in the composition of non-regular workers, and the items of indefinite contract workers are included relatively recent from the 2015 survey, resulting in a time series break in the survey. Considering the high proportion of indefinite contract workers among non-regular workers, it is possible that estimation bias may appear in the period prior to 2015 when indefinite contract workers were not included in the calculation of the proportion of non-regular workers. However, this is a problem that arises from the limitation of survey data, thus it is expected that more meaningful analysis results can be derived if research data that can supplement the limitations are secured in the following studies.

Given that the purpose of human resource management is to improve the productivity of the organization through the motivation of the members of the organization, the most important human resource management practice is appraisal and compensation. In particular, as creativity, cooperation, and innovation have recently begun to be emphasized in companies, changes in appropriate performance evaluation has become a major issue. In order for such a change in the evaluation system to work effectively, it is most important for members of the organization to think positively and accept it. This means that apart from whether the results of the assessment are reasonable and reliable, the results must meet the actual criteria acceptable to the person who wishes to utilize the results. Until now, studies on evaluation acceptability have mainly been applied with the equity theory and the goal setting theory. 'A' airline, which is the subject of this study, uses a relative evaluation system like most other South Korean companies. Based on relative deprivation theory, therefore, this study focuses on the acceptability of employees for the personnel evaluation system, and aims to explore how the acceptance of appraisal affects their performance. In addition, moderating effects of organizational culture type stemmed from Quinn's competing value model was examined in this relationship. A survey of 200 flight crews of 'A' company, one of the South Korea's leading airlines, found that the higher their acceptance of personnel evaluation results, the stronger their customer service performance. This led to the necessity of managing the acceptability of members' personnel evaluations, at least for service sector entities such as airlines. It was also found that only performance culture among various types of organizational culture significantly have an impact on evaluation acceptability and service performance, especially the weaker the performance culture, the stronger the impact of evaluation acceptability on service performance. It means that too much emphasis on goal setting, achievement rate under the relative evaluation system, or too differential compensation based on the evaluation results can create a sense of relative deprivation, which can have a negative effect of reducing evaluation acceptability and service performance. Finally, theoretical and practical implications of research were presented. In particular, from a practical point of view, South Korean companies competitively introduced Western meritocracy to ease the seniority-based HR system, and the relative evaluation system is also part of the meritocratic HR system. This goal-oriented system has also enhanced emotional engagement and organizational performance through sound competition, but it can also enhance the degree of turnover by strengthening excessive competition among employees. In spite of several limitations, however, this study is meaningful in that it identified the positive relationship between acceptability of appraisal and service performance, and furthermore, it proved the moderating effect of the performance culture, which raised alarm about the problems of the evaluation system due to excessive meritocracy of airlines and even South Korean companies.
