近年來平台商業模式與網路交友的盛行，使得許多網路交友平台應運而生。平台的收費模式不以傳統使用者付費的觀念建立，而是以整體平台的互動作為收費的考量，以較優惠或是免費的方式來吸引會引起正向跨邊網路效應的使用者加入，讓他們作為平台的被補貼方，藉此吸引平台的付費方群體加入。 本研究以雙邊平台的觀點來研究網路交友平台是如何設計讓使用者願意加入此平台、如何設計互動機制讓平台上雙方群體進行互動，如何訂定合適的管制讓使用者能方便使用並信任此平台上使用者的真實性，讓適當的顧客匯集。即使同為網路交友平台，其交友的目的、交友的模式也有所不同，因此本研究先探討各交友平台是如何設計互動模式，來促進使用者間的交流，並比較各平台的不同之處。 理解平台的互動機制後，接著探討平台的補貼準則。因為各網路交友平台的設計不同也使得補貼準則有所差異，透過文獻裡所述的補貼準則來分析平台是透過哪種方式來向使用者進行收費，以及分析使用者願意支付費用的原因。 透過幾個交友平台的個案分析，本研究觀察到雖都為網路交友平台，但是其交友的機制都會因其設計理念、交友目的而有所不同。因此本研究整理出哪些補貼準則被應用在網路交友平台上，而各交友平台如何設計收費時機在互動模式上，以理解網路交友平台的整個收費訂價的方式。 / Platform business model and online dating has become popular in recent years, therefore more and more online dating platforms are being set up. Platform pricing model is not set up by user charge alone, how users interact on the platform is also considered. Platform controller attract users who can cause positive cross-side network effect by offering them better price so that they can attract users who are willing to pay the fee. This research depends on two-side market theory to explain how online dating platforms attract users to enter their platforms, design interaction mechanism and set rules to allow users to use platforms easily. Depending on different dating purposes, every online dating platform has its own design. Therefore, this research discusses how different online dating platforms design interaction mechanism and compare the differences between them. After understanding how platforms design interaction mechanism, platform pricing model is then discussed. Every platform has its own pricing model, because of different design. This research analyzes platform pricing model by subsidy rules from previous studies, and why users are willing to pay. By analyzing several online dating platform cases, this research concludes that platforms have different interacting mechanisms because of website design purpose and user dating purpose. This research demonstrates which subsidy rules are used on online dating platform and how these platform design charge timing in order to understand online dating platform pricing model.
