## 1 Introduction  
The rise of globalization is an ideal time to expand your company's size and global reach. For businesses looking to expand, there are plenty of opportunities to take advantage of, such as adding global human resources or increasing the volume of information to help build a company's brand positioning. However, to truly go global, adequate preparation is indispensable [1]. The two most critical steps in this process are product localization and internationalization. Although localization and internationalization both fall into the category of \"globalization\", there are still some differences between the two, which we will explore further below. Internationalization is a corporate strategy focused on maximizing the adaptability of products and services [2; 3]. The progress of science and technology has ushered in the era of globalization. This study takes Taiwan's CNC industry as the research object. The full English name for CNC is computer numerical control. Therefore, CNC is a method that leverages the precise and powerful computing capabilities of computers to control machines for precision machining. Machines referred to as CNC machines, including CNC machine tools, CNC lathes, and CNC milling machines, all rely on computer calculations for their processing operations. CNC not only enables greater flexibility and automation, but also expands the realm of precision processing possibilities, such as the direct conversion of 3D design drawings into CNC codes through CAD/CAM software such as the mastercam for immediate processing. The operating principle of CNC machines is to translate the programs authored by engineers into movement instructions and carry out precise machining on the designated target [4; 5]. Leveraging the efficient experience accumulated by Taiwan's CNC (computer numerical control) machinery companies, coupled with Taiwan's economic environment, and other factors, corporate internationalization has become the path to sustainable development for every company. Enterprise internationalization is one of the most important issues in the field of strategic management [6]. Therefore, companies must delve into various areas, including strategy, marketing, finance, and technology. For example, companies can improve corporate performance through different international strategies, international marketing, and investments in various international markets. Many studies emphasize the advantages of corporate internationalization. It provides businesses with an operational competitive advantage, allowing them to expand into overseas markets, leverage intangible assets and market power, spread risks, and gain access to a cost-effective workforce. This includes international trade, which involves shipping products to different regions and countries, as well as using research and development, innovative product displays, online marketing, magazine media, and other promotional advertising to increase company visibility and improve business performance. Historically, research on the business models of Taiwanese CNC companies has been limited. Whether it is the export of complete machines or key parts, Taiwan occupies a vital position in the global CNC industry. This study aims to determine the relative importance of factors that influence business strategy [7]. This paper uses questionnaire statistics and data analysis to conduct strategic research on Taiwan's CNC machine tool industry. The findings indicate that internationalization and the application of various strategies, directly or indirectly, affect a company's business performance. These results are consistent with past related research, revealing how accumulated experience and capabilities in international trade, R&D, and technology, affect the operating performance of the CNC machine tool industry, which is a reflection of the degree of internationalization of enterprises. Internationalization is still the key growth strategy for the CNC machine tool industry [8; 9].
