However, form the scope of sustainable tourism, it covers a lot of area such as pollution , resource use, wildlife, and etc. And as for the operator, some of them recognize the sustainability as a concern or are ignorant about the terminology. So as we know that the first time put forward in sustainability is at 1969 but until now it is a major issue. So it is hard to conduct in a meaningful ,effective way.

Bigger is not always better. Instead of creating a lot of indicators, the policy maker and researchers should pay attention on smaller sets of items. Therefore, in this article, the research using the method of meta-analysis through previous researches so that to figure out what are the key indicators and whether it contribute into achieving the sustainable tourism.

Based on my understanding, because the masses of indicators or principles do not help a lot in conducting the sustainable tourism project. On the one hand, the operators may have enough ability to choose the right option according the real situation. It is more likely to obfuscate people than enlighten them. On the other hand, when take actions on sustainable tourism development, it takes a lot of cost including time, fund, energy, and etc. However, as for the enterprises level , it is tough to do two or more things at once. For instance, some hotel with little fund can not update the high-technology green machine such as solar system, which contributing on minimize the negative impacts on environment.

What is more, people are more likely to choose the dimensions or indicators which is familiar with and is easy to act. However, it is essential to explore the actual conditions. For instance, unlike the effect of economic sustainability is significant and quick, the outcome of the social or cultural aspects are minimal and unconspicuous. So the operators or bosses who are less responsible of environmental sustainability may not take action on it. However, only focus on any one part of dimension may lose way of achieving long term sustainable development. 

Based on my understanding, simplicity is the key. What we should next is to identify and clarify all the indicators and separate into core parts and peripheral parts. We need to get the principal contradiction of the main issues. For instance, during a period, there is a shortage of electricity, which means fewer electricity quotas, and in order to sustainably develop, hotels must take steps to arrange the electricity quantities. What is more, it also depend on the current policy and all the enterprises should follow it. For example , the national policy about guiding the way to promote the sustainable development which is made though careful considerations and research. It means all industries including tourism industry should work out together.

  In the end, through the analysis of these various studies, seven dimensions related to tourism within framework for sustainable tourism management, four of which are important and focus on them, namely the economic, social, environmental and cultural dimensions.  The other three dimensions are marginal and are political, technological and management. 

It is important to note that these indicators are to be characterized by assessability, so that companies can easily measure their current status and progress toward their goals.

Most indicators can be implemented and evaluated at the enterprise level, and operators have direct control over some indicators, such as control of water pollution, energy waste, waste emissions, sex tourism, etc. There are also many indicators that require action by governments and visitors, calling on businesses to act together to have an impact on their communities.

So what we should do is stop constantly creating new indicators. Identify a set of smaller, more actionable, and manageable core indicators of sustainable tourism.
