In recent years, pavement distresses have been caused by diverse factors such as spalling, deterioration of repaired sections, blow-up, and alkali aggregate reaction due to changing climate environment of a concrete pavement and its construction and maintenance conditions (supply of materials, increase in use of de-icers, etc,). As a leading repair method for deteriorated concrete pavements, partial-depth repair is implemented in accordance with guidelines of material properties for joints of a concrete pavement and field application evaluation systems, but still some of the repaired sections become deteriorated again at an early stage due to poor construction quality and failure of response to environmental impacts. Distresses that can be corrected with partial-depth repairs are largely divided into those of repair materials and of the existing pavement bonded to repair materials, and combined distress of repair materials and the existing pavement. Although re-repair methods should be different by distress type and scale than conventional pavement repair methods, appropriate repair methods and guidance for re-repairs have not been in place so far, and therefore currently, re-repair practices follow the existing manual of partial depth repairs. Therefore, this study evaluated concrete bond characteristics by removing method and repair scope for an experimental section of frequently distressed pavements to determine a re-repair scope and method for deteriorated partial depth repair sections of concrete pavement, the number of which has increased over time.

The global diffusions of free trade agreements have encouraged an increasing number of companies to participate in foreign markets. However, export firms fall behind big data-based customers in international export markets. The gap between the needs of export markets and the capabilities of export companies is broadening. Marketing capabilities are export firms’ ability to understand what target customers want and develop tactical marketing actions and allocate available resources, and achieve export performance (Day 1994; Vorhies and Morgan, 2003). Export firms have to enhance marketing capabilities to narrow the gap (Day, 2011). This study investigates marketing capabilities, export marketing strategies, and their relationships with export performance of the export companies in an industrial complex in South Korea. This study tries to find how marketing variables impact the performance of export firms through the relationships among them. Marketing literature examined that the suitability between marketing capabilities and export marketing strategy is important because of its impact on export performance. Export marketing literature reviewed that export firms’ characteristics such as international experience, firm size, firm age, and export intensity, firm level of market orientation are considered positively related to export performance. Especially for inexperienced and small and medium-sized firms, which have limited marketing resources to achieve successful export performance, the right choice of export marketing, export marketing strategy, and export performance is indispensable. The purpose of this paper is to investigate the moderating effects of export firms’ characteristics on the interactive linkages within marketing capability, export marketing strategy, and export performance. Our first focus in this study is the relationships between marketing capabilities and export strategies and both export marketing strategy and export performance. We discuss their relationships with each other and with export firms’ performance. We develop testable hypotheses as shown in Fig.1. The final samples we used are 104 manufactured export firms in S. Korea. Next, as a result of testing, based on the relationships of having positive effects, we identify the moderating effects of export firms’ characteristics. Our research model proposes that marketing capabilities affect export marketing strategies and ‘specialized marketing capabilities’. These affect the overall export performance. We therefore hypothesize that H1: Marketing organizational capability is positively related to (a) export marketing strategy and (b) specialized export marketing capability. H2: Marketing human resource capability is positively related to (a) export marketing strategy and (b) specialized export marketing capability. H3: Marketing financial capability is positively related to (a) export marketing strategy and (b) specialized export marketing capability. H4: Marketing infrastructure is positively related to (a) export marketing strategy and (b) specialized export marketing capability. H5: Export marketing strategy is positively related to (a) specialized export marketing capability and (b) export performance. H6: Specialized export marketing capability is positively related to export performance. The results of our PLS-SEM analyses are as follows. Our results support H1b, linking marketing organizational capability and specialized export marketing capability. Marketing infrastructure was found to be positively related to both export marketing strategy and specialized export marketing capability, supporting H4a and H4b, respectively. We also observed that export marketing strategy a positive link with specialized export marketing capability and export performance, supporting H5a and H5b, respectively. However, no support is found for H2, H3, and H6. Moderating Effects of Export firms’ Characteristic Factors We tested how export firms’ characteristics moderate the relationships described in our research model (Hypotheses1-6) We used the moderate factors such as export product (final product vs. parts), customer (domestic vs. overseas, company (manufacturer vs. vendor), employment size (less than 100 person, 100 to300, more than 300), sales(less than $46 million, $46 million to $182 million, more than $182 million), export intensity (less than 50% vs. more than 50%) The moderating effects of export firms’ characteristics on the relationships within our research model are discussed (see Figure 1). Four of 30 moderating hypotheses for export firms’ characteristics were supported. The more number of employees and Greater sales volume strengthened the relationships between marketing infrastructures and export marketing strategies. Higher foreign customer strengthened the relationships between marketing infrastructure and specialized export marketing capability. Greater final products strengthened the relationships between export marketing strategies and export performance. However, the relationships between marketing organizational capability and specialized export marketing capability and between export marketing strategy and specialized export marketing capability were not significantly changed with export firms’ characteristic factors. There are no moderating effects on the types of firm and the types of export intensity. The results of this research suggest that the export companies should consider the choice of export marketing strategies the most important factor to achieve high export performance. This study indicates that policy makers for export companies in S. Korea should develop export assistant programs based on export firms’ characteristic factors such as the number of employee, sales volume, the type of customer, and the type of export product. Following limitations of this research should be noted. First, in addition to the manufacturing industry, more researches should be done in other industries. The findings of this study will ensure more validation. Second, to assess the export performance of export firms, this study uses the subjective opinion of respondent about the degree of export performance because of the difficulties of obtaining financial data. The objective financial data should be used to ensure more objectiveness for this research. Third, this study relies on survey data related to the export companies within an industrial complex area in S. Korea. It should be extended to other regions.
