The document discusses infrastructure development and its relationship to state domestic product growth in India. It analyzes infrastructure investment and spending patterns across Indian states. Key findings include: 1) Large disparities exist in per capita GDP and infrastructure investment across states; 2) "Growth states" continue outpacing others but their growth is moderating; 3) Legacy poor performers like Bihar and Uttar Pradesh remain behind but Rajasthan is improving; 4) State spending on infrastructure focuses on economic, social, and specific project categories with amounts varying significantly between states.

2. Introduction
A major area of concern for sustaining the real gross domestic product (GDP) growth in India has been
lack of adequate infrastructure, which can support the growth process. Realizing this, Government of
India as well as the State Governments has ventured into making heavy investment in infrastructure
especially from the First Five-Year Plan onwards. The major focus of infrastructural investment has been
on irrigation, transportation, electric power, agricultural markets, etc between different regions as well
as in terms of agricultural growth. On the verge of 12th Five Year Plan (will commence in 2012-13), it is
necessary to look into the performances across the states as well as the country as a whole.
Scope of Research Project
The research project will identify various parameters of measuring infrastructural health of all states of
India through factor analysis and will analyze relations between above mentioned parameters and
macroeconomic factor like state GDP or industrial production. With the help of statistics, it will also
establish an econometric model to describe the relationship as well as degree of correlation among
various factors (trend analysis).
Literature Survey
At present various comparative studies on state wise performance is available. Some part of research
devoted to the comparison of pre reform and post reform regime (economic reform of 1991-92 is
concerned here), whereas some were concentrated on forecasting of economic factors. Resources are
also focused on analysis of a particular segment (e.g. agricultural infrastructure) of a specific state.
B.B. Bhattachrya and S. Sakthvel’s analysis of the growth performance and structural changes in
domestic product of Indian states in the last two decades reveals that the development process has
been uneven across states. It also argues that preconception of so called growth states may be wrong.
They also established an inverse relationship between population growth and income growth at the
state level in the recent years.
L. Venkatachalam (2003) recognizes the need of focus on broader and long-term sustainable
infrastructure. He advises on understanding of changing operating environment caused by economic
reform and increasing importance of private sector initiative.
Dr. K. A. Familoni, in his paper The Role of Economic and Social Infrastructure in Economic Development:
A Global View; pointed out Economic and Social Infrastructure as the basic foundation on which the
superstructure of development and growth can be put up. They play a vital role in the development of
developed as well as developing nations. Development is by far attainable in a continuous, steady,
quantitative and qualitative ways when the very basic foundation is strong.
Sarnambar Roy recommends that Indian States will have to put stress on Additional Resource
Mobilization (ARM) measures, phasing out of socially irrelevant subsidies and Effective Debt
Management (EDM), in his creditability analysis of states.

3. K. N. Murty and A. Soumya (IIM-B, 2009), in their paper on public investment in infrastructure in India,
have analyzed the likely macroeconomic effects of changes in public investment in infrastructure in
India. They blamed the crowding out effect as private investment is unable to meet the desired level.
Sources of Data and Limitations
The data for the research purpose is collected from Centre for Monitoring the Indian Economy (CMIE)
database, Directorate of Economics & Statistics of respective State Governments, and for All-India --
Central Statistical Organization (CSO). Base year for GDP/SDP’s are taken as 1999-00. This data set has
some limitation. The data refer only to expenditure on government projects and on private corporate
sector projects and excludes investment in the household or unorganized sector (about 33% of total
investment in the economy). Secondly, the investment expenditure reported is the total expenditure for
completing each project, not the expenditure by each project in a year. Therefore the investment
expenditure is in fact spread across years. Finally, the data are collected from various sources as well as
it is not available for some particular states (specifically some of the north-east states). Unavailability of
data in any particular case is taken care by either exclusion of the corresponding parameter or
appropriate assumption based on past data.
1. Understanding of Infrastructure
1.1 Definition and Categorization
Infrastructure is the services and utilities derived from the set of public works that normally has been
produced and maintained by the public sector, even if it may be produced in the private sector. Water
supply, electricity, sanitation, transportation, telecommunications, irrigation dams, regulated markets
and banks are some of the examples of infrastructure for public consumption and use. The agricultural
infrastructure includes all of the basic services, facilities, equipment, and institutions needed for the
economic growth and efficient functioning of the food and fiber markets. As far as nature of
infrastructure is concerned, there are different kinds of infrastructure such as economic infrastructure,
social infrastructure, agricultural infrastructure, financial infrastructure, technological infrastructure etc.
defined in broader terms. But this classification does not signify that each dominates at the cost of
others, rather they are complementary to each other and are indispensable and connected part of
economic development. Economic theory argues that benefits derived from all these kinds of
infrastructure jointly are greater than that of the sum of benefits from each category of individual
infrastructure. In other words, the net benefit of providing diverse kinds of essential infrastructure
together tend to generate more amount of net benefits than that of providing a single infrastructural
facility.
1.2 Importance of Infrastructure
The strong positive correlation between the level of infrastructure and the economic development has
been a well-established fact in the concurrent economics literature. In Keynesian macroeconomic
model, the income or the output in the economy originates from the level of investment made in the
economy. It should be noted that out of all the four factors contributing to income of a nation namely,
government expenditure, consumption expenditure, investment expenditure and net income from
abroad, income from investment comes both from investment expenditure especially by private
individuals as well as from government spending. In spite of the income in the Keynesian model refers to
AMRP | 3
4. short-term income, usually measured on annual basis, the investment made also comprise long-term
investment such as investment in basic infrastructural facilities. Since the model is based on the notion
that there is a direct positive relationship between income and the investment, investment in
infrastructure is economically reasonable.
2. Regional Disparity in Absolute and Relative Economic Terms
There are 29 states and 6 Union territories in the country (considering Delhi as a state). Disparities in
various socio-economical factors can be observed among the states. Geographic location, natural
resources, existing infrastructure, political environment as well as degree of economic reform are the
rationale behind widely varied per capita SDP across states.

5. Figure 1: Inflation Adjusted Per- Capita SDP across States (in Rs.)
Before drawing any conclusion regarding current economic performance of the states, some factors
needs to be taken care:
• Delhi and Goa are not comparable with other state (Because of their small size and political-
economic importance, they do not represent the diversity of a state)
• Political instability, geographical barrier and consequently poor infrastructure affect SDP for north-
east states and Jammu & Kashmir. In spite of this they are ahead of some central states in terms of
year on year growth, though the overall production as well as per-capita is far less than national
average
AMRP | 5
6. • “Growth States” like Punjab and Haryana continues to deliver superior performance, but growth has
rather moderated for others like Maharashtra and Gujarat. Concurrent economic research argues
that these two states are already achieved a certain scale of per-capita production with a
considerable size of economy, and growth rate seems to be quiet impressive while comparing with
states with small size and less matured economy
• Legacy of the so called BIMARU states (Bihar, Madhya Pradesh, Rajasthan and UP) as a consistent
group of poor performers, continues with only exception- Rajasthan. Bihar and Uttar Pradesh and
Madhya Pradesh performed very poorly, growing much more slowly than the average, but the other
members of this group, Rajasthan have performed reasonably well.
• Regional disparity in absolute term can be observed by wide variation of per-capita output of states
(Figure 1). But the more interesting finding is the degree of dispersion in growth rates increased very
significantly in the recent years. The coefficient of variation of the growth rates increased from 0.15
in the period 1985-89 (before economic liberalization of India) to .31 in the current period 2006-09.
3. State Government Expenditure Pattern on Infrastructure Sector
State government expenditures on infrastructure can be categorized in to three main areas namely
economic infrastructure services, social services and specific infrastructure projects pertaining to local
improvement. A brief description of these categories follows:
Based on a paper on ‘Evaluating Investment on Basic Infrastructure’, B.E. Aigbokhan gives examples of
economic infrastructure
Public Utilities
Power, Telecommunication, Piped water supply and piped gas, Sanitation and
sewage, solid waste collection and disposal
Public Works Roads, Major dam and canal works for irrigation and drainage, and other transport
projects like urban and interurban railways, urban transport, seaports and
waterways and airports
Role in the It provides services that are part of the consumption bundle of residents; large-scale
Economy expenditures for public works increase aggregate demand and provide short-run
stimulus to the economy; and it serves as an input into private sector production,
thus boosting output and productivity. The provision of economic infrastructure can
expand the productive capacity of the economy by increasing the quantity and
AMRP | 6
7. quality of such infrastructure thereby accelerating the rate of economic growth and
enhancing the pace of socio-economic development.
Social infrastructures and their role as defined in the same paper:
Education Education is a very important source of economic growth. Even though education
may be a social investment, it is also an economic investment since it enhances the
stock of human capital.
Human Realistic and reliable indicator of modernization or development than any other
resource single measure. It is one of the necessary conditions for all kinds of growth – social,
development political, cultural or economic
Health Health is one of the major determinants of labour productivity and efficiency. Public
health measures include the improvement of environmental sanitation both in rural
and urban areas, removal of stagnant and polluted water, slum clearance, better
housing, clean water supply, better sewage facilities, control of communicable
diseases, provision of medical and health services especially in maternal and child
welfare, health education, family planning and above all, for the training of health
and medical personnel
State-wise specific infrastructure projects are actually categorized in to above two but funding of the
projects does not purely come from government expenditure, rather it is executed on PPP (public-
private partnership), BOT (build-operate-transfer) etc various models
Though the investment pattern can be broadly generalized into these categories, relative investment
varies among states. The average distribution of expenditure in the year 2008 is approximately 17.43%,
27.14% and 49.50% respectively for the above mentioned areas and the trend is followed in subsequent
year (Figure 2). In fact, a growing preference is implementing projects with a specific goal, rather than
taking the general way of running long term programs. Where most of the developed states mostly
adopting the project based approach and their expenditure often beyond planned limit, states from
north- east and “BIMARU’ states are being failed to take the initiative (Figure 3).

From above data it can be concluded that almost every state are investing a certain % of their SDP for
industry purpose, though the ratio of investment varies for different states. It can be concluded that
growth in SDP certainly affects the industrial activity of a state in almost same way (the correlation
coefficient of spending in industrial sector as a % of SDP over the two years being 0.902). Further
analysis shows that both industrial investment and gross output growth have a positive correlation with
SDP growth.
Figure 4: Industrial investment as a % of SDP is almost fixed in recent years,
though they vary in absolute terms

12. Now the question remains if change in SDP does have any impact on state government and private
sector activities in infrastructure sector. The following table summarizes state-wise infrastructure
activities under implementation (data is not available for some of the north east states)

The findings shows that the growth rate of combined investment of government and private entities is
almost un-correlated with SDP growth rate (correlation factor being ~.05). This result can be mostly
attributed to long term nature of projects where the benefits achieved from it spread across years after
commencement of the project. Also some amount of investment goes for in terms of economic theory
which stresses on more focus on ‘social’ infrastructure (subsidies, cap on outflow of funds) which is
quite different from generic infrastructure in terms of various factors.
5. The Determinants of Growth in the States
AMRP | 12
13. The rate of investment is generally regarded as one of the most important factors explaining growth in
any economy and it is therefore appropriate to consider whether inter-state differences in growth are
associated with differences in the rate of investment in individual states. The growth rate of SDP would
be explained in terms of the common explanatory variables traditionally used like the magnitude of
investment in states, industrial activity and the factors of infrastructure index.
g= C +a* independent var. which is a linear equation where C and a constant
Several separate regression equations (g= C +a* independent variable where C is a constant and a is the
intercept) which are to be estimated in which the dependent variable in each case was
g = growth of SDP, while the independent variables were
1. IPUB (cumulative expenditure in public sector projects as a ratio of SDP),
2. IPVT (cumulative expenditure in private sector projects as a ratio of SDP)
3. ITOT=IPUB+IPVT.
4. IGO (increase in gross output of all industries)
5. IINV (increase in gross investment in all industries)
7. V (percentage of villages electrified in the base year)
9. T (tele-density).
5.1 Investment Ratios at the State level
Three separate regression equations were estimated in which the dependent variable in each case was g
= growth of SDP in 2006 to 2009, while the independent variables were IPUB, IPVT and ITOT which already
defined above. The results are reported below
g= 0.152 - 0.06366 IPUB R2 = 0.040955
g = 0.137756 + 0.010789 IPVT R2 = 0.1649
g = 0.137876 +0.010141 ITOT R2 = 0.0264
No significant relationship can be found between the variation in growth across states and the variation
in the public investment ratio while, the private investment ratio proves to be extremely considerable
(coefficient has the expected positive sign). This variable explicate nearly one- sixth (16%) of the
variation in growth for different states.
The above result does not imply that public investment is not important. There may be large errors in
the data-set because of factors mentioned earlier (especially inclusion of future investment in
unfinished projects is likely to introduce a larger error the more inadequately managed the investment
programme). Incomplete projects due to lack of funding and delays may not fuel the growth as
expected.
As private investment is subject to greater financial control the data error arising from a large number of
unfinished and under-funded projects is likely to be much smaller. Because of efficient use of resource
and time, private investment is more directly correlated with growth. It can be concluded that private
AMRP | 13
14. investment matters and under-performing states needs to be focused to ensure private sector
participation for development initiatives.
5.2 Industrial Activity
Considerable part of a states investment is devoted for industrial sector. Though private sector is
dominant participant, it is supported by governments which provide the basic frame-work as well as
investments. Two factors presented here are IGO (increase in gross output of all industries) and IINV
(increase in gross investment in all industries)
g= 0.120971 + 0.061133 IGO R2 = 0.05985
g = 0.122652 + 0.012 IINV R2 = 0.170444
The above relationship re-establishes the fact that a state’s capability of representing itself as an
attractive destination for investment and providing a business conductive environment would add to its
economic growth.
5.3 Quality of Infrastructure
The CMIE has calculated a composite index of the relative infrastructure quality of different states based
on 13 separate components. The individual components are : per capita electric power, percent of
villages electrified, railway route length per 000 sq.km., surfaced road length per 000 sq.km., unsurfaced
road length, handling capacity of major ports, gross irrigated area as % of cropped area, tele-density plus
the following per lakh of population: bank branches, post offices, primary schools, hospital beds, and
primary health centers. Each indicator is computed for each State relative to the all India average=100.
The composite index is the weighted sum of individual indices. (Details: CMIE 1997)
As the composite index is not available for recent periods, some of the individual components are tested
for the impact on growth in the states by estimating separate regression equations. The independent
variables in this case are growth in % village electrification (V) and growth in tele-density (T)
g= 0.136157 + 0.096952 V R2 = 0. 1292
g = 0.139103 + 0.39027 T R2 = 0.02444
The positive relationship between growth and the two infrastructure related parameter (village
electrification and tele-density) broadly matches with expectations. Significance of these factors leis in
their origin- government expenditure and consumption expenditure which are direct contributor to a
state’s growth.
6. Conclusion
Statistical results have been achieved somewhat mixed result. They generate expected confirmation
that change in the private investment ratios are positively and notably correlated with change in growth.
They also give corroboration that certain factors of infrastructure are associated with variations in
growth. They also recommend that public investment is not as certainly allied with growth as apparently
AMRP | 14
15. expected. Although, all these results, including the lack of an important relationship in some cases, are
subject to limitation of the data available (like absence of composite infrastructure index).
7. Future Plan of Work
More work needs to be done in improving the data available on possible factors which may help explain
the variations in growth across states, which will provide the statistical analysis the desired robustness.
After examining the factors and their relative importance, this study is to be extended further to devise
a strategy for slow growth states for achieving economic development while addressing their funding
issues.
