The research study aims to improve the prior conducted literature by concentrating on the precursors of innovation in marketing and its impact on building a sustainable competitive market. The paper intends to address this by examining the following variables using a mixed-method approach.Design/methodology/approachThe researcher employed the mixed methods particularly the sequential explanatory design to explain and interpret the quantitative data collected from 89 business owners/managers using Jamovi Software while the qualitative data were collected through an in-depth interview conducted with 10 SME owner-managers of new and established businesses in Angeles City, Pampanga using Taxonomic Coding Scheme. The sequential explanatory design was used to explain and interpret quantitative results by collecting and analyzing follow-up qualitative data.FindingsThis study investigates the relationship between marketing capabilities and marketing innovation towards sustainable competitive advantage of micro-small and medium enterprises in the Philippines through mixed method approach. For quantitative result, the study found that marketing competency significantly influenced marketing innovation. The result shows that all SMEs have enough people in place who are capable of implementing marketing innovation activities and use new technology like the use of information technology.

MSMEs exhibit this innovation such as product, price, place, and promotion can create a distinctive position in the market towards sustainable competitive advantage. The paper also tested the mediation effect of marketing innovation that influences the relationship between marketing competence and sustainable competitive advantage. Most of the hypotheses posited were supported. For qualitative data, it was revealed that these SMEs through their key informants and key leaders are open to innovations thus, willing to learn by establishing networks with customers and other managers/business owners to expand and improve their business. The food business in Pampanga is highly competitive, and most of the SMEs are engaged with it.

Hence, it indicated that marketing competency significantly influences sustainable competitive advantage, which can be achieved through marketing innovation. In this study, the researcher analyzed the influence between marketing competence and marketing innovation to achieve a sustainable and competitive market.Research limitations/implicationsThere were certain limitations of this research study. First, the lack of panel data limits the investigation of causality that is instrumental in substantiating the findings. Second, the proposed conceptual framework offers a deeper understanding of innovation performance, examining how integrating activities of the R&D department, human resource department, and marketing department affect innovation commercialization will likely provide more meaningful insights. Moreover, finally, future studies may go beyond the scope of our study to examine (1) food and meat processing, (2) agriculture, hunting, and forestry, (3) hotels and restaurants, (4) mining and quarrying, (5) wholesale and retail trade, (6) transport, storage communication.Practical implicationsTo remain relevant in this extraordinary time, this paper suggests a support instrument to offer vital data on different categories of innovation to the foodservice sector SMEs in Angeles City to embrace and implement new innovative methods in their practices. The key practical implication of this research, therefore, is the requirement for small and medium business owner-managers to improve their technical capability to realize the full benefits, particularly in terms of more responsive and user-centered, data-driven marketing personnel.Social implicationsThese findings may influence positive social change by contributing to more effective and efficient marketing practices in small and medium firms that can lead to better financial performance, higher survival rates, and a healthier economic system. This study demonstrates that SME owner-managers require new skillsets to overcome the barriers to adopting technology for marketing. This primary capability is a prerequisite to the competitive advantage of the business, yielding to brand equity, business growth, and marketing dominance.Originality/valueThis study used a sequential explanatory mixed-methods strategy to determine the significant variables. This paper addresses an interesting and practical issue related to the impact of marketing capabilities and marketing innovation towards sustainable competitive advantage of micro-small and medium enterprises in the Philippines using mixed method approach.
