This newspaper comprehensive foreign media reported that the official website of the World Bank issued a post on January 12th，There is a gap between many developed economies and the full factor productivity of developed economies，To find the cause of this gap，Cross -country differences in the distribution of enterprises have become the focus of scholars' attention。Some scholars think，The generation of this phenomenon is related to the "disappearing intermediate layer" and market friction Bet365 lotto review and policy distortion that is not conducive to the development of medium -sized enterprises。The so -called "disappearing middle layer"，Generally refers to the employment market、Enterprise Development、Consumption mode、The head effect and differentiation of individual wealth are intensified。

In order to study whether the full factor productivity among different countries is related to the distribution of enterprise scale，Researchers conducted research in 4 countries in Africa, southern Sahara，Comprehensively collected corporate information of these countries，Among them, it also includes information from informal enterprises。They found，"Disappearing Intermediate" is an elusive concept，Bet365 app download The statement of the existence of the relevant binary cover up the correlation of the problem，But from the data obtained from the research，There is indeed a "disappearing middle layer" in the employment market，The large number of enterprises that are not formal may be the cause of this problem。

Researchers discovered，Countries involved in the research institute，Most workers are employed by small or large companies，The number of employment in medium -sized enterprises is far lower than small or large enterprises。This phenomenon reflects the inherent features of the scale distribution of the state -owned enterprises in the sample。In the field of employment，"Disappearing Intermediate" is not caused Bet365 lotto review by a large number of large foreign companies or state -owned enterprises in the sample country，It is likely to be related to informal enterprises，Because in these countries，The number of non -formal enterprises is far more than regular enterprises。Researchers also observed，There is no problem of "disappearing intermediate layer" among workers who entered the employment market for the first time，Enter small、The number of workers working in medium and large enterprises is not large.，But after a period of time，Some workers who have worked in medium -sized enterprises have transferred to large enterprises or middle -scale enterprises themselves developed into large enterprises，and originally in small、bet365 best casino games The number of people who work in non -formal enterprises change small。

From the perspective of researchers，"Disappearing Intermediate" can become a useful indicator，Because it shows that there is a possibility of re -assigning labor between enterprises。People should not simply interpret the "disappearing middle layer" as a lack of medium -sized enterprises，Instead, it should be linked to economic efficiency and scale economic，Control the size of the offenders by reducing the cost of enterprise registration and strengthening law enforcement，Promoting the development and productivity of regular enterprises。
