2. Introduction The relationship between equity and economic growth has long attracted the interest of researchers. Whether inequality helps or harms future economic growth? The issue remains contentious. Past studies find differing effects when considering rich and poor countries, regions versus nations and so on.

3. Economic theories that hypothesize that income inequality harms growth can be grouped into three categories:

4. First, the political-economy approach hypothesizes that in unequal societies redistribute resources from rich to poor. Increase in income inequality inhibits economic growth.

5. Second, income inequality retards growth by encouraging social conflict within societies. In this manner, inequality results in more crime and unlawful activities, which threaten investment and property rights.

6. Third, the imperfect capital market hypothesis suggests that inequality is associated with credit barriers that reduce the ability of lower classes to invest in physical and human capital.

8. Economic inequality: comprises all disparities in the distribution of economic and income. The term typically refers to inequality among individuals and groups within a society or among countries. Economic Inequality generally refers to equality of outcome, and is related to the idea of equality of opportunity.

9. Gini Coefficient: Developed by an Italian statistician Corrado Gini in the 1910s, Gini Gini Coefficient: Developed by an Italian statistician Corrado Gini in the 1910s, Gini Coefficient is commonly used to indicate income inequality in a society. Gini Coefficient is a number which has a value between zero and one. As the value of the Coefficient rises, the higher the degree of income inequality in a society becomes Coefficient is commonly used to indicate income inequality in a society. Gini Coefficient is a number which has a value between zero and one. As the value of the Coefficient rises, the higher the degree of income inequality in a society becomes

10. A Kuznets curve: A Kuznets curve: Simon Kuznets argued that levels of economic inequality are in large part the result of stages of development. Kuznets saw a curve-like relationship between level of income and inequality, now known as Kuznets curve.

12. Economic growth: Economic growth: Several recent economists have investigated the relationship between inequality and economic growth using econometrics. In their study for the World Institute for Development Economics Research, They conclude that too much equality (below a Gini coefficient of 0.25) negatively impacts growth due to "incentive traps, free-riding, labour shirking, and high supervision costs

13. Robert Barro wrote a paper arguing that inequality reduces growth in poor countries and promotes growth in rich ones.

A number of other researchers have derived conflicting results, some concluding there is a negative effect of inequality on growth.

19. From the empirical studies, we find that there is rather robust negative relationship between inequality and economic growth in the developed countries and poor countries. Except some contradictions From the empirical studies, we find that there is rather robust negative relationship between inequality and economic growth in the developed countries and poor countries.

20. Conclusion Studies of inequality and economic growth have been well conducted by many other scholars and organizations. But the inequality-economic growth debate remains unsettled. We see those contradictions in relationship between Kuznetz curve, Gini coefficient, economic growth and so on.
