经济开放度与一个国家或地区的资源禀赋特点、经济发展阶段、企业的国际竞争能力等因素密切相关,同时受到国际经济形势和国内经济关系格局的影响。如何量化和测度经济开放度,国内外的有关专家学者已提出不少判断指标,但尚未达成共识,至于提出完整的指标体系,则分歧更大。有学者对地区经济外向度的测算,主要依据进口比率、出口比率、对外借款比率和外商直接投资比率,具有一定的科学性,但指标筛选和权数确定的某些方法不符合当前通用的方式。如果将进口与出口的分列,将对外贸易在经济外向度测算中的比重过分加大。由此的测算结果也与人们的观念相差较大。对此,我们基于对国内外众多方法理论的比较借鉴,力求简便易行, The degree of economic openness is closely related to the resource endowment characteristics of a country or region, the stage of economic development, and the international competitiveness of enterprises. At the same time, it is affected by the international economic situation and the pattern of domestic economic relations. How to quantify and measure the degree of economic openness, relevant experts and scholars at home and abroad have put forward a lot of judgments, but no consensus has yet been reached. As for the complete index system, the differences are even greater. Some scholars have calculated the extrinsic degree of the regional economy mainly on the basis of the import ratio, export ratio, foreign loan ratio and the ratio of foreign direct investment. However, some methods of index screening and weight determination do not conform to the current general methods . If the breakdown of imports and exports, the proportion of foreign trade in the calculation of the degree of economic excesses will be excessively increased. The result of this calculation also differs greatly from people’s concept. In this regard, based on the comparison of many methodologies at home and abroad, we seek to be simple and easy to implement,
