What is non enlarged reproduction, and the prerequisites for expanded reproduction are:

To put it simply, it is a reproduction that does not expand personnel, plant equipment, etc., but only improves production technology or management methods, so as to improve production efficiency.

1. Prerequisites for the expansion of social capital reproduction:

i(c+v+m)>i(c)+ii(c) or i(v+m)>ii(c).

ii(c+v+m)>i(v+m/x)+ii(v+m/x)

The premise is "two redundant".

2. The basic conditions for the realization of the expanded reproduction of total social capital (coordinated development) can be expressed by the formula as follows:

i（v+△v+m/x）==ii(c+△c)

From this basic formula, two basic formulas can be deduced:

1）i(c+v+m)==i(c+△c)+ii(c+△c)

2）ii(c+v+m)==i(v+△v+m/x)+ii(v+△v+m/x)

The core problem of the theory of social reproduction is the realization of the total social product. In the process of analyzing how capitalist expansion and reproduction is carried out, Marx put forward two basic premises on which social reproduction is based from the two perspectives of physical composition and ** composition through the analysis of the total product of the social mega-ruler society.

According to its final use, the total social product is divided into two major categories: the production of means of production and the production of means of production and the production and consumption of means of production The means of production include raw materials, but they are not the same as raw materials, because it also includes the means of labor based on production tools, including mining industry, machinery manufacturing industry, cement, coal, chemical industry and other sectors used for the production of raw materials;

The means of consumption include textiles, medicines, food, papermaking and other production sectors that are produced for daily consumption. The core issue in the smooth implementation of social reproduction is to realize two compensations, namely, compensation for the value of the total social product and material compensation.

The prerequisites for the expansion of reproduction are: First, society must have surplus means of production, that is, all the products produced by the first department can not only compensate for the means of production consumed by the two major departments, but also provide additional means of production for the expansion and reproduction of the two major departments. i.e. i(v+m) > ic.

Second, society must have surplus means of consumption, that is, all the products produced by the second department can not only compensate for the consumption of the two major departments, but also provide additional means of consumption for the expansion and reproduction of the two major departments.

Expanded reproduction (expandedreproduction) What is expanded reproductionExpanded reproduction refers to the reproduction of production on an expanded scale due to the increase in the number of production factors and the expansion of production sites, or the improvement of the quality of production factors and the improvement of use efficiency. Expansion of reproduction for the continuation and development of simple reproduction.

Prerequisites for the expansion of reproduction:

1. I(V+M)>IIC, the first department is the means of production provided by the second department, in addition to meeting the needs of the second department for simple reproduction of the means of production, there must also be a surplus to meet the needs of the two major departments for the expansion of reproduction for additional means of production.

2. In addition to satisfying the needs of workers and investors for their personal consumption expenses during the simple reproduction of the first department, the second department must also have a surplus to meet the needs of the additional workers in the expansion and reproduction of the two major departments. Qi Zhen.

d. Expanded reproduction of connotation;

e. Extended reproduction of epitaxy;

In the Marxist theory of social reproduction, there are two different forms of expanded reproduction, namely, extended reproduction and implicit expanded reproduction. It is of great theoretical and practical significance to clarify what is extended and implicit expanded reproduction and how to correctly handle these two forms of expanded reproduction in socialist economic construction.

Reproduction: Constantly updated and repetitive production.

Simple reproduction: Reproduction that maintains the original scale basis, and the surplus value obtained does not become additional capital (i.e., after deducting the maintenance of the original scale of production, the rest is used for the capitalist's personal consumption).

Simple reproduction refers to reproduction with the same scale of production, and expanded reproduction refers to reproduction with an expanded scale of production.

Capitalist simple reproduction means that the capitalist uses all the surplus value for personal consumption, the amount of capital put into the production process remains unchanged, and the reproduction is repeated only on the original scale. Simple reproduction is the basis and starting point for expanding reproduction, and is an important part of expanding reproduction.

Expanded reproduction: refers to the reproduction of production on an expanded scale due to the increase in the number of factors of production and the expansion of production sites, or the improvement of the quality of factors of production and the increase in the efficiency of use. Accumulation is an important source for expanding reproduction.

Expanded reproduction is further divided into epitaxial type and connotative type of expanded reproduction according to the mode of expansion.

Difference: The main thing is whether the scale is expanded or not. Although both of them are constantly carrying out repeated production, simple reproduction always maintains the original scale, while expanded reproduction is constantly expanding the scale, expanding on the basis of expansion, and so on.

For example, if a leather shoe manufacturer uses the same number of tools, equipment, raw materials and labor every year to produce the same amount of leather shoes, this is simple reproduction; If he adds tools, equipment, raw materials, and hires more labor in the second year, the production of leather shoes also greatly increases, this is the expansion of reproduction.

In order for any society to develop, it must adopt the method of expanding reproduction. However, "a journey of a thousand miles begins with a single step", no matter how production is expanded, it is always based on the original scale and starting point, and only on the basis of completing simple reproduction can we expand and reproduce. Therefore, simple reproduction is the premise and basis for expanding reproduction, and expanding reproduction is the continuation and development of simple reproduction.

1) There are two prerequisites for the expansion of reproduction:

First, (v + m)> cThe sum of the variable capital value and surplus value of the first department must be greater than the constant capital value of the second department in order to provide additional means of production for the expansion of reproduction.

Second, (c + m-m x)> v + m x). The sum of the constant capital and the surplus value for accumulation in the second department must be greater than the sum of the variable capital in the first department and the surplus value of the capitalists for personal consumption, in order to provide additional means of consumption for the expansion of reproduction.

2) There are three limb rulers for the realization of expanded reproduction:

First, the sum of the value of the original variable capital of the first department, the additional value of the variable capital and the surplus value of the capitalists of the department for personal consumption must be equal to the sum of the original constant capital value and the additional constant capital value of the second department. It is expressed by the formula: (v + v + m x) = c + c).

Second, the value of all the products of the first department must be equal to the sum of the constant capital value and the additional constant capital value of the two major departments. It is expressed by the formula as: (C + V + M) = C + C) + C + C).

Thirdly, the value of all the products of the second department must be equal to the sum of the original variable capital value, the additional variable capital value, and the surplus value of the capitalist for personal consumption. It is expressed by the formula as:

c + v + m）=ⅰv +δv + m/x）+ v +δv + m/x）

Of the three implementation conditions, the first condition is the basic condition, and the second and third conditions are derived from the first condition. The three conditions for the realization of the expanded reproduction of social capital together show the importance of maintaining the appropriate proportional relationship between the two major sectors.
