3. Writing the introduction
The introduction of your literature review should provide an overview of existing knowledge of the topic/issue being reviewed and definitions of technical terms or concepts if necessary. It is important for you to explain why the topic/issue is worth reviewing by relating your research focus to the knowledge gaps identified, for example, an understudied area. You should also state clearly the purpose (what the review aims to achieve) and scope of the review (e.g. what aspects of the topic will be covered). The organisational pattern of the review often comes at the end of the introduction.
The following are generally included in the introduction to a literature review:
● background information on the topic/issue being reviewed, including its purpose and significance
● definition/explanation of any key terms
● justification for why a review of the topic/issue is needed
● a statement about the purpose and scope of the review
● a brief outline of your plan for/framework of how the topic/issue is to be reviewed
● an overview of the organisation of your literature review
Example Introduction 1
Energy-savings have raised more and more concerns recently, complying with the exacerbating situation of global warming and energy usage. Light-emitting diode (LED), as a critical approach for energy reduction, plays a pivotal role for energy-savings nowadays. LED is a very essential application and is regarded as the potential substitute for traditional lighting, indicating a promising future with huge convenience and considerable profit. In recent years, the development of the LED industry has skyrocketed. Specifically, the LED industry in China is promisingly profitable as it has been selected as one of the "strategic emerging industries" and has been granted considerable government subsidies. To evaluate the plausibility to make profit, it is of great importance to obtain an all-rounded scope of the market and identify the crucial factors which may promote or impede the development of LED.
This review starts with the current global market as well as Chinese market in terms of the scope and trends of LED development. By adopting a SWOT analysis (i.e. strength, weakness, opportunity and threat), this review discusses some benefits and obstacles of the development of the existing LED market, followed by the potential opportunities for and threats to future development of LED to justify whether it is worthwhile to conduct merger and acquisition transactions.
